JIS G4305 SUS323L Steel Plate | 323L Stainless Steel
What is JIS G4305 SUS323L Steel Plate?
As a stainless steel supplier and China mill-direct exporter, SHH STEEL supplies JIS G4305 SUS323L Steel Plate, also known as 323L stainless steel. SUS323L is a lean duplex (austenitic-ferritic) grade of JIS G4305:2021, the Japanese Industrial Standard for cold-rolled stainless steel plate, sheet and strip. It is a lean duplex grade with 21.50 – 24.50 % chromium, 3.00 – 5.50 % nickel, only 0.05 – 0.60 % molybdenum and 0.05 – 0.20 % nitrogen, with carbon limited to 0.030 %.
SUS323L is the JIS counterpart of the 2304 type. Its limits match UNS S32304 in ASTM A240 (ASTM A240 2304 stainless steel plate), and GB/T 20878 links it to EN 1.4362, supplied as EN 10088-2 1.4362 plate, and to the Chinese grade GB/T 4237 022Cr23Ni4MoCuN S23043 plate.
This page summarises the requirements of JIS G4305:2021 for SUS323L: chemical composition, mechanical properties, surface finishes, standard sizes and the informative heat-treatment conditions of Annex JA. Hot-rolled plate of the same grade is ordered to JIS G 4304:2021, which also lists SUS323L. SHH STEEL quotes either standard and confirms the edition named on the drawing before an order is placed.
SUS323L material specification and SHH STEEL supply scope
| Item | JIS G4305:2021 requirement | SHH STEEL supply |
|---|---|---|
| Standard | JIS G 4305:2021, cold-rolled stainless steel plate, sheet and strip | Full compliance; JIS G 4304:2021 for hot-rolled plate |
| Grade | SUS323L (austenitic-ferritic (duplex)) | Confirmed by heat analysis on the certificate |
| Standard plate sizes (Table 16) | Thickness 0.30 – 20.0 mm; 1 000 × 2 000, 1 219 × 2 438, 1 219 × 3 048 and 1 524 × 3 048 mm | Other sizes by agreement, as Table 16 allows |
| Standard strip thickness (Table 17) | 0.30 – 6.0 mm | Coil and slit strip |
| Surface finish (Table 15) | No.2D, No.2B, BA, HL; polished finishes by the manufacturer’s method | Finish written into the mill order |
| Inspection document | JIS G 0415, inspection certificate 3.1, unless otherwise specified | 3.1 standard; 3.2 with third-party witness on request |
Mechanical properties in JIS G4305 apply to thickness 0.30 mm and above, and the standard notes that properties after heat treatment carried out by the user are not specified. Clause 7 makes intergranular corrosion testing a matter for agreement.
Chemical composition of JIS G4305 SUS323L (heat analysis, %)
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.50 |
| Phosphorus (P) | ≤ 0.040 |
| Sulphur (S) | ≤ 0.030 |
| Nickel (Ni) | 3.00 – 5.50 |
| Chromium (Cr) | 21.50 – 24.50 |
| Molybdenum (Mo) | 0.05 – 0.60 |
| Copper (Cu) | 0.05 – 0.60 |
| Nitrogen (N) | 0.05 – 0.20 |
These limits are the same as those of ASTM A240 S32304. Using PREN = %Cr + 3.3 × %Mo + 16 × %N, the minimum limits give about 22.6.
Mechanical properties of SUS323L in the solution-treated condition (JIS G4305 Table 10)
| Property | Requirement |
|---|---|
| 0.2 % proof stress | ≥ 400 N/mm² |
| Tensile strength | ≥ 600 N/mm² |
| Elongation | ≥ 20 % (thickness ≤ 2.0 mm), ≥ 25 % (over 2.0 mm) |
| Hardness | ≤ 290 HBW, or ≤ 32 HRC, or ≤ 310 HV |
The proof stress is more than twice the 175 N/mm² of SUS304L in Table 8, which lets designers reduce wall thickness compared with austenitic grades.
Surface finishes for SUS323L sheet and plate
| Finish (Table 15) | Description |
|---|---|
| No.2D | Cold rolled, heat treated and pickled (or equivalent); may include a final light pass on dull rolls |
| No.2B | Cold rolled, heat treated, pickled, then lightly cold rolled for a suitable lustre |
| BA | Bright annealed after cold rolling |
| HL | Polished with abrasive of suitable grit to give continuous polishing lines |
JIS G4305 leaves polished finishes such as No.3, No.4, #240, #320 and #400 to the manufacturer’s method, so SHH STEEL writes the finish, the grit and any protective film into the purchase order. For duplex grades, No.2B and No.2D are the usual finishes for sheet and strip; HL and polished finishes are used where appearance matters.
Heat treatment and delivery condition of SUS323L
| Treatment | Condition (Annex JA, Table JA.2) |
|---|---|
| Solution treatment | 950 – 1 100 °C, rapid cooling |
Annex JA is informative. Rapid cooling after solution treatment keeps the austenite-ferrite structure free of the brittle intermetallic phases that can form in duplex steels held at intermediate temperatures, so SHH STEEL asks the mill to record the solution-treatment temperature on the certificate.
Table 19 of JIS G4305 gives a basic mass of 7.80 kg/(mm·m²) for SUS323L, which is used to calculate plate weight (equivalent to a density of 7.80 g/cm³). Lead time from the mill is normally 30 – 40 days after order confirmation, depending on size, finish and rolling schedule.
Key characteristics of 323L stainless steel
- Lean duplex: low nickel and molybdenum, with 0.05 – 0.20 % nitrogen.
- Proof stress ≥ 400 N/mm², tensile strength ≥ 600 N/mm².
- Same chemistry limits as ASTM A240 S32304 (2304).
- Low carbon (≤ 0.030 %) for welded construction.
- Magnetic, like all duplex grades.
- Density 7.80 g/cm³ (JIS G4305 Table 19).
SUS323L equivalent grades
| System | Grade | Comment |
|---|---|---|
| ASTM / UNS | ASTM A240 S32304 (Type 2304) | Same chemical limits |
| EN 10088-2 | EN 10088-2 1.4362 (X2CrNiN23-4) | Cross-referenced in GB/T 20878 Table C.1 |
| China | GB/T 4237 S23043 (022Cr23Ni4MoCuN) | Cross-referenced in GB/T 20878 Table C.1 |
For pressure equipment, see EN 10028-7 1.4362 pressure vessel plate. For more corrosion resistance, ASTM A240 Type 2205 sheet and plate or JIS G4305 SUS329J3L steel plate is the next step up.
Applications of JIS G4305 SUS323L Steel Plate
Euro Inox lists these typical applications for the EN equivalent 1.4362, noting high strength and corrosion resistance:
- Chemical industry equipment
- Biogas digesters
- Load-bearing building components
Lean duplex is often compared with 304L and 316L where higher strength allows thinner sections.
SUS323L compared with related JIS G4305 grades
The table compares SUS323L with the JIS G4305:2021 grades that buyers most often consider alongside it. Chemistry is taken from Tables 3 – 7 and the minimum mechanical properties from Tables 8 – 14 of the standard, all in the condition in which the grade is normally supplied.
| JIS G4305 grade | Cr % | Ni % | Mo % | Other | 0.2 % proof stress, N/mm² | Tensile, N/mm² | Elongation, % |
|---|---|---|---|---|---|---|---|
| JIS G4305 SUS821L1 | 20.50 – 21.50 | 1.50 – 2.50 | ≤ 0.60 | Cu 0.50 – 1.50, N 0.15 – 0.20 | 400 | 600 | 20 / 25 |
| SUS323L | 21.50 – 24.50 | 3.00 – 5.50 | 0.05 – 0.60 | N 0.05 – 0.20 | 400 | 600 | 20 / 25 |
| JIS G4305 SUS329J3L | 21.00 – 24.00 | 4.50 – 6.50 | 2.50 – 3.50 | N 0.08 – 0.20 | 450 | 620 | 18 |
| JIS G4305 SUS304L | 18.00 – 20.00 | 9.00 – 13.00 | – | C ≤ 0.030 | 175 | 480 | 40 |
| JIS G4305 SUS316L | 16.00 – 18.00 | 12.00 – 15.00 | 2.00 – 3.00 | C ≤ 0.030 | 175 | 480 | 40 |
SUS323L and SUS821L1 are the two lean duplex grades of JIS G4305; both have 400 N/mm² minimum proof stress, more than twice that of SUS304L and SUS316L. SUS329J3L is the 2205-type step up with 2.50 – 3.50 % molybdenum. SHH STEEL can quote the grades in this table side by side when a buyer is still choosing between them.
SUS323L to JIS G4305 (cold rolled) or JIS G4304 (hot rolled)?
SUS323L is listed in both JIS G4305:2021 (cold-rolled plate, sheet and strip) and JIS G4304:2021 (hot-rolled plate, sheet and strip). The chemistry and the mechanical property tables are the same in both standards, but the product range, finish and tolerances differ:
| Item | JIS G4305 (cold rolled) | JIS G4304 (hot rolled) |
|---|---|---|
| Standard plate thicknesses (Table 16) | 0.30 – 20.0 mm | 2.0 – 35.0 mm |
| Standard plate sizes | 1 000 × 2 000, 1 219 × 2 438, 1 219 × 3 048, 1 524 × 3 048 mm | Same four sizes |
| Standard strip thicknesses (Table 17) | 0.30 – 6.0 mm | 2.0 – 9.0 mm |
| Surface finish (Table 15) | No.2D, No.2B, BA, HL | No.1 (hot rolled, heat treated and pickled) |
| Plate thickness tolerance | Table 20, or ET / ST on request | Classes A, B or C (Tables 20 – 22); B and C use an addition to thickness for calculated mass |
As a rule, thin sheet and anything that needs a bright or brushed surface is ordered to JIS G4305, while heavier plate for fabrication is ordered to JIS G4304. Sizes outside the tables are possible by agreement in both standards. SHH STEEL confirms which standard and finish suit the part before quoting.
Corrosion resistance of SUS323L
A common way to rank resistance to pitting is the pitting resistance equivalent number, PREN = %Cr + 3.3 × %Mo + 16 × %N. Calculated from the JIS G4305 limits, SUS323L has a PREN of about 22.5 at the minimum of every range and about 29.7 at the maximum. PREN is a ranking tool, not a guarantee of performance in a given environment, and actual heats normally sit between these values; the certificate analysis gives the real figure for each heat. SHH STEEL can calculate the PREN of the heat offered from its certificate before the order is confirmed.
Duplex steels such as SUS323L combine chromium, molybdenum and nitrogen with a two-phase structure. The IMOA duplex guide reports that duplex grades resist chloride stress corrosion cracking much better than Type 304L and 316L in accelerated laboratory tests, which is one of the main reasons they are chosen for warm chloride service. The same guide warns that sigma phase can form between about 700 and 1 000 °C and that nitrides and carbides can form between 450 and 800 °C, so correct annealing and rapid cooling are essential to keep the corrosion resistance shown by PREN. With little molybdenum, its PREN is closer to that of 316L than to 2205, so it is usually chosen where strength and stress corrosion resistance matter more than pitting resistance.
Where resistance to intergranular corrosion must be demonstrated, clause 7 of JIS G4305 lets the purchaser specify one of four test methods: JIS G 0571 (oxalic acid etch test), JIS G 0572 (ferric sulphate – sulphuric acid test), JIS G 0573 (65 % nitric acid test) or JIS G 0575 (copper sulphate – sulphuric acid test). One test piece is taken per heat and heat-treatment lot. SHH STEEL writes the chosen method and acceptance criterion into the mill order when a project requires it.
Physical properties of SUS323L
| Property | Typical value (Euro Inox, Tables of Technical Properties, EN 1.4362) |
|---|---|
| Density | 7.8 g/cm³ |
| Modulus of elasticity at 20 °C | 200 GPa |
| Mean thermal expansion 20 – 200 °C | 13.5 × 10⁻⁶ /K |
| Mean thermal expansion 20 – 400 °C | 14.0 × 10⁻⁶ /K |
| Thermal conductivity at 20 °C | 15 W/(m·K) |
| Specific heat at 20 °C | 500 J/(kg·K) |
| Electrical resistivity at 20 °C | 0.80 Ω·mm²/m |
JIS G4305 gives physical data only as the basic mass of 7.80 kg/(mm·m²) in Table 19. The other values are typical figures published for EN 1.4362 (Euro Inox) and are given for design guidance only; they are not acceptance requirements for SUS323L. On request, SHH STEEL can pass on the producing mill’s own data sheet for the heat supplied.
Welding, forming and machining SUS323L
SUS323L is welded with the usual arc processes. The IMOA duplex guide notes that duplex weld metal resists hot cracking much better than austenitic weld metal, but that the procedure must let the heat-affected zone cool quickly to avoid intermetallic phases. As a general guideline it limits the interpass temperature to 150 °C for lean and standard duplex grades, and recommends that this limit be fixed when the procedure is qualified and monitored in production. Modern duplex grades are balanced to about 40 – 50 % ferrite, and the procedure should keep the weld and heat-affected zone close to this balance.
For joining duplex to duplex, the IMOA guide lists E2307, E2209 or E309L filler metals. Because of 475 °C embrittlement of the ferrite, duplex steels should not be used for long periods above the temperatures allowed by the pressure-vessel design code; IMOA quotes 315 °C as the ASME limit for common duplex grades. In cold forming, duplex plate needs more force than 316L and shows more springback because of its higher proof stress, and its relative machinability is lower than that of austenitic grades, so tool settings should be adjusted.
SHH STEEL can deliver SUS323L cut to size, bevelled or pre-formed through its processing partners, so that the fabricator receives parts ready for welding.
- Keep interpass temperature at or below 150 °C.
- Euro Inox lists 1.4362 and 1.4462 filler materials for the EN equivalent 1.4362.
- Pickle welds after fabrication.
Dimensional tolerances for SUS323L plate and sheet (JIS G4305)
JIS G4305:2021 clause 9 sets the tolerances for cold-rolled plate, sheet and strip, and SHH STEEL checks thickness at the positions the standard defines before shipment. Thickness tolerances for plate are given in Table 20 and depend on thickness and width:
| Thickness (mm) | Width < 1 250 mm | Width 1 250 – 1 600 mm |
|---|---|---|
| 0.30 – < 0.60 | ± 0.05 | ± 0.08 |
| 0.60 – < 0.80 | ± 0.07 | ± 0.09 |
| 0.80 – < 1.00 | ± 0.09 | ± 0.10 |
| 1.00 – < 1.25 | ± 0.10 | ± 0.12 |
| 1.25 – < 1.60 | ± 0.12 | ± 0.15 |
| 1.60 – < 2.00 | ± 0.15 | ± 0.17 |
| 2.00 – < 2.50 | ± 0.17 | ± 0.20 |
| 2.50 – < 3.15 | ± 0.22 | ± 0.25 |
| 3.15 – < 4.00 | ± 0.25 | ± 0.30 |
| 4.00 – < 5.00 | ± 0.35 | ± 0.40 |
| 5.00 – < 6.00 | ± 0.40 | ± 0.45 |
| 6.00 – < 8.00 | ± 0.50 | ± 0.50 |
| 8.00 – < 10.0 | ± 0.60 | ± 0.60 |
| 10.0 – < 16.0 | ± 0.70 | ± 0.70 |
| 16.0 – 25.0 | ± 0.80 | ± 0.80 |
Tighter thickness tolerances can be ordered with the symbols ET (Table 22) or ST (Table 23), and narrower width tolerances with EW (Table 26). Plate width tolerance (Table 24) is +10 / 0 mm for lengths up to 3 500 mm, and plate length tolerance (Table 27) is +10 / 0 mm for thickness under 10 mm and lengths up to 3 500 mm. Flatness is measured on request: Table 28 allows 15 – 20 mm per 3 500 mm length, or 3 – 6 mm when the special flatness symbol EF is ordered.
For hot-rolled SUS323L plate ordered to JIS G 4304, the tolerances of that standard apply. SHH STEEL states the tolerance symbols on the quotation so that the buyer knows exactly which table the plate will be measured against.
Testing, inspection and marking of SUS323L
Clause 11 of JIS G4305 sets the test rules. Chemical analysis follows JIS G 0404 and JIS G 0320, and a product (check) analysis to JIS G 0321 can be requested by the purchaser. For mechanical tests, one sample is taken from plate or strip of the same heat and the same heat-treatment condition, and one test piece is used for each test.
- Tensile test to JIS Z 2241 at 23 ± 5 °C, using test piece No. 4, No. 10 or No. 13B (No. 14A, 14B or 5 also allowed).
- Hardness test to JIS Z 2243-1 (Brinell), JIS Z 2244-1 (Vickers) or JIS Z 2245 (Rockwell), at 23 ± 5 °C.
- Bend test to JIS Z 2248 where the grade has a bend requirement; the manufacturer may omit it, but the material must still meet it, and it must be done if the purchaser asks.
- Inspection of chemistry, mechanical properties, surface finish, dimensions and appearance under clause 12; corrosion resistance only when specified.
Under clause 13 each plate or bundle is marked with the grade symbol, dimensions, any special tolerance or flatness symbols (ET, ST, EW, EF), the surface finish, the heat-treatment symbol where applicable, the manufacturer’s name or mark, and the heat or inspection number. Clause 14 makes the inspection document JIS G 0415 type 3.1 unless another type is ordered; SHH STEEL checks the marking against the certificate before shipment, and a third-party inspector arranged by SHH STEEL can witness the tests when a 3.2 document is required.
How to order SUS323L plate and sheet
A complete enquiry avoids delays and wrong deliveries. For SUS323L we recommend stating:
- Standard and edition: JIS G 4305:2021 (cold rolled) or JIS G 4304:2021 (hot rolled), grade SUS323L.
- Product form: plate, sheet, coil or strip; thickness, width and length, or coil inner diameter and weight.
- Tolerance and flatness symbols if tighter than standard (ET, ST, EW, EF).
- Surface finish from Table 15 (No.2D, No.2B, BA, HL) or a polished finish with grit and protective film.
- Heat-treatment condition, and any intergranular corrosion test method (JIS G 0571 – 0575).
- Inspection document type (JIS G 0415 3.1 by default, 3.2 if third-party witness is needed).
- Any dual certification required, for example to ASTM A240 or EN 10088-2, and any product analysis or PMI.
- Packing, marking and destination port; SHH STEEL can add customer marking or bar codes on request.
SHH STEEL reviews every enquiry against these points and confirms in writing anything that the mill cannot meet before the order is placed.
How to calculate the weight of SUS323L plate
Table 18 of JIS G4305 calculates plate mass from the basic mass in Table 19, which for SUS323L is 7.80 kg per mm of thickness per m² of area. The basic mass is multiplied by the thickness in millimetres to give the unit mass in kg/m², then by the plate area in m², and the result is rounded as the table specifies.
| Example | Calculation | Mass |
|---|---|---|
| SUS323L, 3.0 × 1 219 × 2 438 mm | 7.80 × 3.0 × (1.219 × 2.438) | about 69.5 kg per sheet |
Invoiced weight may be calculated (theoretical) or actual (weighed), and this should be agreed at the order. SHH STEEL states which method is used on the quotation, and the SHH STEEL packing list shows both the calculated and the actual weight of each bundle.
Why choose SHH STEEL for SUS323L
As a SUS323L supplier, we find that buyers usually worry less about price than about getting the right material on time. The table below lists the concerns we hear most often and how SHH STEEL deals with each one.
| Buyer concern | Risk | How SHH STEEL handles it |
|---|---|---|
| Grade substitution | A different lean duplex with other limits is supplied. | Grade, UNS number and chemistry are checked on the certificate and by PMI. |
| Phase balance | Slow cooling harms toughness. | Solution treatment and rapid cooling are recorded on the certificate. |
| Elongation by thickness | Thin sheet tested against the wrong elongation value. | The 20 % / 25 % thickness split of Table 10 is checked on the certificate. |
| Minimum order | Mills set high minimums for less common grades. | Orders are consolidated so smaller lots can join a mill rolling where the mill makes the grade. |
| Delivery tracking | Delays at rolling, annealing or testing are found too late. | A dedicated person follows the schedule and reports progress at each stage. |
SHH STEEL also offers steel cutting services, bending and forming services, a third-party testing service with partner laboratories, and a worldwide shipping service. See our full range of stainless steel sheets and plates.
FAQ
- What is SUS323L equivalent to?
- SUS323L is the JIS counterpart of the 2304 type. Its chemical limits are the same as those of UNS S32304 in ASTM A240, and GB/T 20878 Table C.1 links it to EN 1.4362 (X2CrNiN23-4) and to the Chinese grade 022Cr23Ni4MoCuN, ISC S23043. Because the JIS and A240 chemistry limits are identical, dual certification depends mainly on meeting both sets of mechanical requirements. SHH STEEL checks this for each heat and can supply SUS323L, 2304 and 1.4362 with the matching certificate. Every SUS323L plate shipped by SHH STEEL carries an inspection document to JIS G 0415, type 3.1 by default. Purchase orders should name JIS G4305, its edition, the grade, the thickness and the inspection document required, so the certificate can be checked against the same tables.
- What is the chemical composition of JIS G4305 SUS323L?
- JIS G4305:2021 sets the following heat-analysis limits for SUS323L: Carbon (C) ≤ 0.030; Silicon (Si) ≤ 1.00; Manganese (Mn) ≤ 2.50; Phosphorus (P) ≤ 0.040; Sulphur (S) ≤ 0.030; Nickel (Ni) 3.00 – 5.50; Chromium (Cr) 21.50 – 24.50; Molybdenum (Mo) 0.05 – 0.60; Copper (Cu) 0.05 – 0.60; Nitrogen (N) 0.05 – 0.20. Its low molybdenum and nickel make it a lean duplex grade. Elements not listed are not added intentionally; where the standard asks for the content of optional elements to be reported, it appears on the inspection certificate. SHH STEEL checks every certificate against these limits before shipment and can arrange an independent check analysis by a partner laboratory. Where a project specification adds requirements beyond JIS G4305, they should be written into the enquiry so the mill can confirm them before rolling.
- What are the mechanical properties of SUS323L plate?
- In the solution-treated condition, JIS G4305 Table 10 requires SUS323L to have a 0.2 % proof stress of at least 400 N/mm², a tensile strength of at least 600 N/mm² and an elongation of at least 20 % up to 2.0 mm and 25 % above 2.0 mm. Hardness must not exceed 290 HBW, 32 HRC or 310 HV; only one hardness method is needed, chosen by the manufacturer unless the order specifies it. These values apply to thickness 0.30 mm and above, and proof stress applies when the purchaser asks for it. The proof stress is more than twice that of SUS304L. SHH STEEL checks the tensile and hardness results on the 3.1 inspection certificate for every heat before the material is released.
- How is SUS323L heat treated?
- Annex JA of JIS G4305 gives solution treatment at 950 – 1 100 °C with rapid cooling as the example heat treatment for SUS323L. The annex is informative, so it shows typical conditions rather than mandatory limits, and the mill applies its own qualified practice within the requirements of the standard. Rapid cooling matters because duplex steels held at intermediate temperatures can form brittle phases. SHH STEEL supplies SUS323L in the heat-treated condition stated on the order and asks the mill to record the treatment on the inspection certificate, so the fabricator knows the starting condition of the material. The figures quoted are the limits of JIS G4305; the actual values for a given heat are those reported on the mill test certificate.
- What sizes and finishes of SUS323L can SHH STEEL supply?
- JIS G4305 lists standard plate thicknesses from 0.30 mm to 20.0 mm and sheet sizes from 1 000 × 2 000 mm to 1 524 × 3 048 mm; strip is listed from 0.30 mm to 6.0 mm. The standard finishes are No.2D, No.2B, BA and HL, with polished finishes made by the manufacturer's method. Other sizes are possible by agreement, and hot-rolled plate is ordered to JIS G 4304. SHH STEEL confirms with the mill which sizes it can roll in SUS323L, then offers cut-to-size blanks, slit coil or full plates. Lead time is normally 30 – 40 days. If a drawing names more than one standard, the material must meet each of them, and the certificate should state every standard it claims.
- Is SUS323L magnetic?
- Yes. SUS323L is a duplex (austenitic-ferritic) stainless steel, and the ferrite in its two-phase structure makes it magnetic, unlike the solution-treated 300-series austenitic grades. The magnetic response does not indicate a defect or a wrong grade; it is normal for duplex steel. For this reason a magnet cannot be used to tell SUS323L from ferritic or martensitic steels, and grade checks should rely on the certificate and positive material identification (PMI). Its lean chemistry does not change this behaviour. Magnetic response can also vary slightly with the ferrite content, which depends on chemistry and heat treatment. SHH STEEL carries out PMI on request before shipment. Any supplementary test, such as a product analysis or a corrosion test, has to be agreed at the enquiry stage because it cannot be added after delivery.
Conclusion
JIS G4305 SUS323L Steel Plate (323L stainless steel) is the lean duplex grade of JIS G4305 and the counterpart of 2304 and 1.4362, giving 400 N/mm² minimum proof stress with low nickel and molybdenum. SHH STEEL supplies it with full JIS G4305 compliance, 3.1 inspection certificates and optional third-party testing, with a normal lead time of 30 – 40 days.
