JIS G4305 SUS304LN Steel Plate | 304LN Stainless Steel
What is JIS G4305 SUS304LN Steel Plate?
As a stainless steel supplier and China mill-direct exporter, SHH STEEL supplies JIS G4305 SUS304LN Steel Plate, also known as 304LN stainless steel. SUS304LN is a nitrogen-alloyed low-carbon austenitic grade of JIS G4305:2021, the Japanese Industrial Standard for cold-rolled stainless steel plate, sheet and strip. It is a low-carbon (0.030 % maximum) 18Cr-10Ni steel with 0.12 – 0.22 % nitrogen added for strength, so it keeps the weld-zone advantage of SUS304L while reaching a higher proof stress than SUS304.
SUS304LN plate is ordered where the corrosion behaviour of 304L is wanted together with higher design strength. Its American counterpart is Type 304LN (UNS S30453) in ASTM A240, and its European counterpart is EN 10088-2 1.4311 plate; in China the matching grade is GB/T 4237 022Cr19Ni10N S30453 plate.
This page summarises the requirements of JIS G4305:2021 for SUS304LN: 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 SUS304LN. SHH STEEL quotes either standard and confirms the edition named on the drawing before an order is placed.
SUS304LN 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 | SUS304LN (austenitic) | 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 between purchaser and manufacturer.
Chemical composition of JIS G4305 SUS304LN (heat analysis, %)
| Element | Content (%) |
|---|---|
| Carbon (C) | ≤ 0.030 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulphur (S) | ≤ 0.030 |
| Nickel (Ni) | 8.50 – 11.50 |
| Chromium (Cr) | 17.00 – 19.00 |
| Nitrogen (N) | 0.12 – 0.22 |
The composition follows JIS G4305:2021 Table 3 as reproduced by the Japan Stainless Steel Association (JSSA). Nitrogen of 0.12 – 0.22 % is the defining element: it raises strength without raising carbon, so the grade keeps the low-carbon resistance to sensitisation in welds.
Mechanical properties of SUS304LN in the solution-treated condition (JIS G4305 Table 8)
| Property | Requirement |
|---|---|
| 0.2 % proof stress | ≥ 245 N/mm² |
| Tensile strength | ≥ 550 N/mm² |
| Elongation | ≥ 40 % |
| Hardness | ≤ 217 HBW, or ≤ 95 HRBW/HRBS, or ≤ 220 HV |
For comparison, Table 8 sets 205 N/mm² proof stress for SUS304 and 175 N/mm² for SUS304L, so the nitrogen addition gives SUS304LN about 40 % more minimum proof stress than SUS304L.
Surface finishes for SUS304LN 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 austenitic grades, No.2B is the usual finish for cold-rolled sheet and BA is used where a bright surface is needed.
Heat treatment and delivery condition of SUS304LN
| Treatment | Condition (Annex JA, Table JA.1) |
|---|---|
| Solution treatment | 1 010 – 1 150 °C, rapid cooling |
Annex JA is informative. Rapid cooling from the solution-treatment range keeps carbon and nitrogen in solution and gives the non-magnetic austenitic structure in the annealed condition.
Table 19 of JIS G4305 gives a basic mass of 7.93 kg/(mm·m²) for SUS304LN, which is used to calculate plate weight (equivalent to a density of 7.93 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 304LN stainless steel
- Low carbon (≤ 0.030 %) for welded construction, with 0.12 – 0.22 % nitrogen for strength.
- Proof stress ≥ 245 N/mm² against 175 N/mm² for SUS304L (JIS G4305 Table 8).
- Elongation ≥ 40 %, the same as SUS304, so forming behaviour stays typical of 18-8 steels.
- Density 7.93 g/cm³, the same basic mass as SUS304 in Table 19.
- Dual certification to ASTM A240 304LN is possible when a heat meets both sets of limits.
SUS304LN equivalent grades
| System | Grade | Comment |
|---|---|---|
| ASTM / UNS | Type 304LN, UNS S30453 (ASTM A240) | Close; A240: Cr 18.0 – 20.0 %, Ni 8.0 – 12.0 %, N 0.10 – 0.16 %, Si ≤ 0.75 % |
| EN 10088-2 | EN 10088-2 1.4311 (X2CrNiN18-10) | Close; Cr 17.5 – 19.5 %, Ni 8.5 – 11.5 %, N 0.12 – 0.22 % |
| China | GB/T 4237 S30453 (022Cr19Ni10N) | Cross-referenced to S30453 and 1.4311 in GB/T 20878 Table C.1 |
Because ASTM A240 caps nitrogen at 0.16 % and requires 18.0 % minimum chromium, a heat for dual JIS/ASTM certification must sit at 18.0 – 19.0 % chromium and 0.12 – 0.16 % nitrogen. A240 sets 515 MPa tensile and 205 MPa yield strength for S30453. For pressure equipment in Europe, see EN 10028-7 1.4311 pressure vessel plate.
Applications of JIS G4305 SUS304LN Steel Plate
Euro Inox lists these typical applications for the EN equivalent 1.4311:
- Pressure vessels in the chemical, dairy and brewing industries
- Pumps and fittings
- General service needing good general corrosion resistance with higher strength than 304L
Where nitrogen strengthening is not needed, JIS G4305 SUS304L steel plate is the simpler choice; see also JIS G4305 SUS304 steel plate.
SUS304LN compared with related JIS G4305 grades
The table compares SUS304LN 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 SUS304 | 18.00 – 20.00 | 8.00 – 10.50 | – | C ≤ 0.08 | 205 | 520 | 40 |
| JIS G4305 SUS304L | 18.00 – 20.00 | 9.00 – 13.00 | – | C ≤ 0.030 | 175 | 480 | 40 |
| SUS304LN | 17.00 – 19.00 | 8.50 – 11.50 | – | N 0.12 – 0.22 | 245 | 550 | 40 |
| JIS G4305 SUS316L | 16.00 – 18.00 | 12.00 – 15.00 | 2.00 – 3.00 | C ≤ 0.030 | 175 | 480 | 40 |
| JIS G4305 SUS316LN | 16.50 – 18.50 | 10.50 – 14.50 | 2.00 – 3.00 | N 0.12 – 0.22 | 245 | 550 | 40 |
Nitrogen gives SUS304LN 245 N/mm² minimum proof stress against 175 N/mm² for SUS304L, while keeping the same 40 % elongation. SUS316LN is the molybdenum-bearing counterpart. SHH STEEL can quote the grades in this table side by side when a buyer is still choosing between them.
SUS304LN to JIS G4305 (cold rolled) or JIS G4304 (hot rolled)?
SUS304LN 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 SUS304LN
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, SUS304LN has a PREN of about 18.9 at the minimum of every range and about 22.5 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.
SUS304LN has the general corrosion resistance of the 18-8 grades: good in atmospheric, fresh-water and many food and chemical environments, but without molybdenum it is less resistant to pitting in chloride solutions than the 316 family. Its low carbon limits sensitisation in welds, which is why it is used for welded pressure equipment.
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 SUS304LN
| Property | Typical value (Euro Inox, Tables of Technical Properties, EN 1.4311) |
|---|---|
| Density | 7.9 g/cm³ |
| Modulus of elasticity at 20 °C | 200 GPa |
| Mean thermal expansion 20 – 200 °C | 16.5 × 10⁻⁶ /K |
| Mean thermal expansion 20 – 400 °C | 17.5 × 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 | 0.73 Ω·mm²/m |
JIS G4305 gives physical data only as the basic mass of 7.93 kg/(mm·m²) in Table 19. The other values are typical figures published for EN 1.4311 (Euro Inox) and are given for design guidance only; they are not acceptance requirements for SUS304LN. On request, SHH STEEL can pass on the producing mill’s own data sheet for the heat supplied.
Welding, forming and machining SUS304LN
SUS304LN is an austenitic steel and is welded readily by TIG, MIG, plasma and manual metal arc processes. Low carbon limits chromium carbide precipitation in the heat-affected zone, so welded parts normally keep their resistance to intergranular corrosion without post-weld heat treatment. Austenitic steels have a higher thermal expansion and lower thermal conductivity than carbon steel, so distortion control (tacking sequence, fixtures, balanced welding) matters more.
For the EN equivalent 1.4311, Euro Inox lists 1.4316, 1.4455 and 1.4551 as filler materials. Austenitic plate forms well because of its high elongation, but it work-hardens quickly, so forming forces rise as deformation increases and machining needs sharp tools, positive rake and continuous cuts to avoid a hardened surface layer.
SHH STEEL can deliver SUS304LN cut to size, bevelled or pre-formed through its processing partners, so that the fabricator receives parts ready for welding.
Dimensional tolerances for SUS304LN 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 SUS304LN 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 SUS304LN
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 SUS304LN plate and sheet
A complete enquiry avoids delays and wrong deliveries. For SUS304LN we recommend stating:
- Standard and edition: JIS G 4305:2021 (cold rolled) or JIS G 4304:2021 (hot rolled), grade SUS304LN.
- 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 SUS304LN plate
Table 18 of JIS G4305 calculates plate mass from the basic mass in Table 19, which for SUS304LN is 7.93 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 |
|---|---|---|
| SUS304LN, 3.0 × 1 219 × 2 438 mm | 7.93 × 3.0 × (1.219 × 2.438) | about 70.7 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 SUS304LN
As a SUS304LN 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 | Plain SUS304L without nitrogen is supplied, so strength is too low. | Nitrogen and proof stress are checked on the certificate; a check analysis can be arranged. |
| Dual-standard limits | A heat meets JIS but not A240 nitrogen or chromium. | Both sets of limits are checked before the order when dual certification is needed. |
| Surface damage | Scratches on 2B or BA sheet. | Interleaving paper or PE film and careful packing are written into the order. |
| 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 SUS304LN equivalent to?
- The nearest American grade is Type 304LN, UNS S30453, in ASTM A240, and the European grade is 1.4311 (X2CrNiN18-10) in EN 10088-2. GB/T 20878 links both to the Chinese grade 022Cr19Ni10N, ISC S30453. The limits are close but not identical: A240 requires 18.0 – 20.0 % chromium and 0.10 – 0.16 % nitrogen, while JIS G4305 allows 17.00 – 19.00 % chromium and 0.12 – 0.22 % nitrogen. A heat can be certified to both only inside the overlap. SHH STEEL compares the limits for the customer and can offer dual-certified material where the mill's analysis allows it. Every SUS304LN 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 SUS304LN?
- JIS G4305:2021 sets the following heat-analysis limits for SUS304LN: Carbon (C) ≤ 0.030; Silicon (Si) ≤ 1.00; Manganese (Mn) ≤ 2.00; Phosphorus (P) ≤ 0.045; Sulphur (S) ≤ 0.030; Nickel (Ni) 8.50 – 11.50; Chromium (Cr) 17.00 – 19.00; Nitrogen (N) 0.12 – 0.22. The nitrogen range is what separates SUS304LN from SUS304L. 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 SUS304LN plate?
- In the solution-treated condition, JIS G4305 Table 8 requires SUS304LN to have a 0.2 % proof stress of at least 245 N/mm², a tensile strength of at least 550 N/mm² and an elongation of at least 40 %. Hardness must not exceed 217 HBW, 95 HRBW or 220 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 40 N/mm² above SUS304 and 70 N/mm² above SUS304L. SHH STEEL checks the tensile and hardness results on the 3.1 inspection certificate for every heat before the material is released. 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.
- How is SUS304LN heat treated?
- Annex JA of JIS G4305 gives solution treatment at 1 010 – 1 150 °C with rapid cooling as the example heat treatment for SUS304LN. 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. After welding, the low carbon content means that post-weld solution treatment is not normally required for corrosion reasons; this is decided by the fabricator's procedure. SHH STEEL supplies SUS304LN 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. If a drawing names more than one standard, the material must meet each of them, and the certificate should state every standard it claims.
- What sizes and finishes of SUS304LN 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 SUS304LN, then offers cut-to-size blanks, slit coil or full plates. Lead time is normally 30 – 40 days. The figures quoted are the limits of JIS G4305; the actual values for a given heat are those reported on the mill test certificate.
- Is SUS304LN magnetic?
- SUS304LN is an austenitic stainless steel, and in the solution-treated condition austenitic grades of this type are essentially non-magnetic. Nitrogen is an austenite-forming element, so it helps keep the structure austenitic. Some magnetic response can appear after heavy cold work, at sheared edges or in weld metal that contains a little ferrite, which is normal for 18-8 type steels. If a customer needs a specific magnetic permeability, it must be stated on the order, because JIS G4305 does not set a magnetic requirement. SHH STEEL can arrange permeability testing through a partner laboratory. 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.
Conclusion
JIS G4305 SUS304LN Steel Plate (304LN stainless steel) is the nitrogen-strengthened, low-carbon 18-10 austenitic grade of JIS G4305, combining 245 N/mm² minimum proof stress with the weldability of 304L. 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. Contact SHH STEEL for availability, sizes and a quotation for your SUS304LN requirement.
