EN 10088-2 X2CrMoTi17-1 1.4513 Stainless Steel Plate

EN 10088-2 X2CrMoTi17-1 1.4513 stainless steel plate is a ferritic flat product supplied to EN 10088-2, the European standard for stainless steel sheet, plate and strip for general purposes. The standard lists X2CrMoTi17-1 among its special grades: a low-carbon steel with 16.0 – 18.0 % chromium, 0.80 – 1.40 % molybdenum and a titanium addition that ties up carbon and nitrogen. The molybdenum lifts pitting resistance above that of plain 17 % chromium grades such as 1.4510 or 1.4016, while the steel stays nickel-free and magnetic. In EN 10088-2 it is listed for cold rolled strip and sheet only, up to 8 mm, so most 1.4513 ferritic sheet is thin gauge 2B or BA material for exhaust systems, appliances and trim.

SHH STEEL works as a steel sourcing partner with long-term relationships with Chinese stainless mills that roll titanium-stabilised ferritic grades, including the molybdenum-bearing 17 % chromium types. For large tonnages, the buyer can contract directly with a suitable mill, with SHH STEEL assisting for a modest service fee and handling follow-up and documents. For small orders we consolidate demand, so that 1 – 5 t lots are placed against genuine mill production instead of stock of unknown origin. Each shipment can be released after third-party inspection by TUV, ABS, BV, DNV, CCS or an agency the buyer nominates, and payment by TT or LC is accepted. The rest of this page covers the technical side of EN 10088-2 1.4513 and the steps we take so that the sheet that arrives is the sheet that was ordered.

The table below lists the concerns buyers raise most often when sourcing EN 10088-2 X2CrMoTi17-1 sheet and plate from China, and how SHH STEEL deals with each of them.

1.4513 can be bought under more than one standard, and the right choice depends on the end use. EN 10088-2 is the general-purpose delivery standard; EN 10028-7 1.4513 pressure vessel plate is the route when the steel goes into pressure equipment and needs the properties and testing of EN 10028-7. In American specifications there is no grade with the same titanium-only stabilisation, so a buyer using ASTM A240 has to decide whether Type 436 or Type 444 is acceptable instead.

For most exhaust, appliance and decorative work EN 10088-2 is the natural standard. If the drawing names Type 436 or SUS436L, SHH STEEL compares the limits against 1.4513 before quoting, so any difference in stabilisation or molybdenum range is visible at the start.

Edition note: the values on this page are taken from EN 10088-2:2014. A revised edition (EN 10088-2:2024) has since been published. If your contract names the newer edition, SHH STEEL checks the order against that text before production, and any difference is raised at the quotation stage rather than after rolling.

The 1.4513 chemical composition below is the cast (heat) analysis from EN 10088-2:2014 Table 3. Values are percentages by mass; a single figure is a maximum.

The titanium minimum depends on the actual carbon and nitrogen of the heat. With 0.020 % carbon and 0.015 % nitrogen, for example, the minimum would be 4 × 0.035 + 0.15 = 0.29 % Ti. SHH STEEL checks this calculation on every certificate as part of the 1.4513 chemical composition review, because a heat with too little titanium loses the stabilisation that protects the weld zone.

Product analysis tolerances (EN 10088-2 Table 5)

A product analysis is a check made on the delivered sheet. It is not mandatory under EN 10088-2; it is carried out when agreed at the time of enquiry and order, and SHH STEEL can arrange it through a partner laboratory. The permissible tolerances on the cast limits are:

Where several product analyses are made on one cast, individual results may exceed the maximum or fall below the minimum, but not both for the same element. How a tolerance applies to the calculated titanium minimum should be confirmed in the contract if a product analysis is ordered.

The 1.4513 mechanical properties below are the room-temperature values for the annealed condition in EN 10088-2:2014 Table 9. Only the cold rolled product form is listed for this special grade.

Elongation is measured on an 80 mm gauge length below 3 mm thickness and on a proportional gauge length (5.65√S0) from 3 mm upwards. For bigger sizes the values are to be agreed at the time of enquiry and order. Table 9 records resistance to intergranular corrosion (tested to EN ISO 3651-2) as “yes” in both the delivery and the welded condition.

The proof strength of 200 MPa is lower than that of 1.4521, and close to the softer stabilised ferritics such as EN 10088-2 1.4520 plate, which helps press forming. SHH STEEL can add hardness or extra tensile tests on request.

EN 10088-2:2014 Table 14 gives no elevated-temperature proof strength values for 1.4513. If the steel is used in exhaust parts at high temperature, design data should come from the mill or from the designer’s own data, and SHH STEEL can request mill data where it exists.

X2CrMoTi17-1 plate and sheet are delivered in the annealed condition (+A). EN 10088-2 Table A.3 gives the guideline temperatures:

Annealing at 820 – 880 °C followed by air or water cooling restores a soft, recrystallised ferritic structure after cold rolling. Because titanium binds the carbon and nitrogen, welds and heat-affected zones do not normally need a post-weld anneal to stay resistant to intergranular corrosion.

As with all 17 % chromium and higher ferritics, long exposure around 400 – 550 °C can cause 475 °C embrittlement, prolonged exposure at higher temperatures can form sigma phase, and over-heating coarsens the grain. These effects are general knowledge for the grade family rather than EN 10088-2 requirements. The Annex A temperatures are guidelines; actual furnace settings are chosen by the mill, and we check that the annealed condition is stated on each certificate.

The values below are room-temperature reference figures for X2CrMoTi17-1 1.4513, taken from the physical-property table in Euro Inox, Stainless Steel: Tables of Technical Properties (Materials and Applications Series, Volume 5). They are suitable for design estimates and weight calculation; where a figure is critical, use EN 10088-1 itself.

The low thermal expansion, roughly two thirds of that of austenitic 304, is one reason 1.4513 is used in exhaust systems that cycle between cold and hot, because less expansion means lower thermal stress at welds and hangers.

Molybdenum is what separates 1.4513 from 1.4510 and 1.4520. About 1 % molybdenum raises resistance to pitting by chlorides and to the condensate inside exhaust systems, which is acidic and contains chlorides from road salt. Titanium stabilisation keeps the weld zone free of chromium carbides, so the steel stays resistant to intergranular corrosion in the welded condition.

Where chloride levels are higher, the next step is 1.4521 or ASTM A240 Type 444 sheet and plate, with about 2 % molybdenum. In many applications that otherwise would use austenitic ASTM A240 Type 316L sheet and plate, a molybdenum ferritic can be considered, but the comparison depends on the environment and should be checked case by case. This guidance is general and not part of EN 10088-2.

1.4513 has good weldability for a ferritic stainless steel. The low carbon and titanium stabilisation limit carbide precipitation and martensite formation, so thin sheet can be welded by TIG, MIG, plasma, laser and resistance processes without preheat.

• Keep heat input low to limit grain growth in the heat-affected zone, which can reduce toughness.
• Use a stabilised ferritic filler (for example a molybdenum-bearing titanium or niobium stabilised type) or an austenitic filler such as 316L where toughness is critical.
• Shield the root with argon on tube and pipe welds to avoid oxidation and loss of corrosion resistance.
• Remove heat tint by pickling or brushing on visible or wet parts.
• Post-weld annealing is not normally needed.

These points reflect industry practice for titanium-stabilised molybdenum ferritics rather than requirements of EN 10088-2, which does not specify welding procedures. In the SHH STEEL workshop, blanks and slit strips are cut with clean, burr-free edges so that seam, spot and tube welding run without edge preparation problems.

In the annealed condition 1.4513 ferritic sheet bends and press-forms well, with lower work hardening than austenitic grades. It shows the springback and some ridging typical of 17 % chromium ferritics, so tight radius bending needs allowance and visible parts may need a BA or polished finish. Deep drawing is possible, though softer grades such as 1.4520 are easier for very deep shapes.

Machining is comparable to other stabilised ferritic grades and easier than for austenitic steels; titanium carbonitrides can wear tools a little faster, so sharp tools and steady feeds are recommended. Punching and drilling of thin sheet is routine.

We run our own workshop next to the warehouse, so 1.4513 can be delivered as slit coil, cut-to-length sheets, laser-cut blanks or bent parts instead of raw mill sizes. Details are on our steel cutting services and bending and forming services pages. Protective film can be applied for visible or deep-drawn parts.

Because EN 10088-2 lists 1.4513 only as cold rolled strip and sheet, the supply range is thin gauge.

Thickness tolerances under EN ISO 9445 come in normal and special (closer) classes, so the class should be stated in the order. Flatness and edge condition (mill edge or slit edge) also need to be agreed.

SHH STEEL can supply 1.4513 cold rolled sheet in standard sizes or cut to your drawing, and slit coil to the widths your tube mill or press line requires. Hot rolled plate in this grade is not in EN 10088-2 and is rarely rolled.

Surface finish is ordered by the process route symbols of EN 10088-2 Table 6; trade names from ASTM and JIS are shown for reference. Not every route is available for every grade, and the mill confirms which ones it can supply.

Ferritic grades can show ridging (roping) after forming, which is more visible on bright surfaces. If appearance after forming matters, state it in the enquiry so the mill can adjust processing, and SHH STEEL can apply PVC film to protect the surface.

Many buyers search for the 1.4513 equivalent in American, Chinese and Japanese standards. The short answer is that there is no exact American grade, while the Chinese and Japanese grades are close but not identical.

As a SUS436L equivalent, 1.4513 matches closely on chromium and molybdenum, but JIS allows several stabilising elements, and the molybdenum ranges differ slightly. If a drawing names one grade and the order names another, ask the designer to confirm the substitution. SHH STEEL can provide a comparison of the limits on request.

1.4513 vs 1.4510, 1.4520 and 1.4521

Compared with EN 10088-2 1.4510 plate and EN 10088-2 1.4520 plate, which are molybdenum-free titanium-stabilised grades, 1.4513 adds about 1 % molybdenum for better pitting resistance at a moderate cost increase. 1.4521 has about 2 % molybdenum and goes further. A buyer who needs more corrosion resistance than 1.4510 but not the full step to 1.4521 often ends up with 1.4513.

Typical applications of 1.4513 ferritic plate and sheet include:

• Automotive exhaust systems, especially the cold end: mufflers, tail pipes and connecting tubes
• Exterior and interior trim for vehicles and buildings
• Domestic appliances: washing machine drums, dishwasher panels and cooker parts
• Kitchen sinks and catering equipment
• Water heater housings and lighter-duty water parts
• Lift panels and decorative cladding indoors

Where the part carries pressure, the order should use EN 10028-7 instead. For high-temperature hot-end exhaust parts, a heat-resisting or niobium-stabilised grade may suit better, and SHH STEEL can advise on the alternatives.

Most problems with 1.4513 come from the fact that it is a special grade, rolled by fewer mills, and that molybdenum-free sheet looks exactly the same.

None of these steps is complicated, but they need to be agreed at the start. When you send an enquiry, tell us which of these points matters most to you, and the order will be built around it.

Every 1.4513 order is supported by documents and checks that make the material traceable to the heat:

• Cast analysis with the titanium minimum checked against carbon and nitrogen
• Tensile test on the annealed sheet: Rp0.2, Rm and A
• Intergranular corrosion test to EN ISO 3651-2 when ordered
• Surface and dimensional inspection against EN ISO 9445
• Additional checks through our third-party testing service: PMI, dimensional, flatness and surface inspection

If the order does not name an inspection document, EN 10088-2 requires only a test report 2.2. Because this is rarely enough for automotive or export work, SHH STEEL supplies an EN 10204 3.1 inspection certificate as standard and a 3.2 certificate when an independent inspector (TUV, ABS, BV, DNV, CCS or an agency you nominate) witnesses testing and countersigns the document.

Ordering example and lead time

Following the pattern of the example in EN 10088-2, a typical order line would read: 10 t cold rolled sheet, 1.5 mm × 1 250 mm × 2 500 mm, EN 10088-2, steel X2CrMoTi17-1 (1.4513), process route 2B, inspection certificate 3.1 to EN 10204. Mill production lead time is generally 30 – 40 days from order confirmation, depending on the rolling schedule, the size and the tests requested; as a special grade, 1.4513 may need a little more planning to fit into the rolling schedule. Consolidated small lots follow the same mill schedule, and we send progress updates at rolling, testing and packing.

• Mill relationships: long-term cooperation with Chinese stainless mills helps us secure competitive pricing and steadier delivery for 1.4513 and related ferritic grades.
• Direct mill contracts: for larger tonnages you can contract directly with a suitable mill, for a modest service fee, while we handle follow-up and documents.
• Order consolidation: 1 – 5 t lots are combined so they can be placed against genuine mill production.
• Own workshop: slitting, cut-to-length, laser cutting, bending and protective film before shipment.
• Inspection and certificates: third-party inspection by TUV, ABS, BV, DNV, CCS or your nominated agency, with EN 10204 3.1 or 3.2 certificates.
• Flexible payment: TT, LC or a combination of both.
• Port logistics: coil and sheet are packed seaworthy with heat-number labels and shipped through our worldwide shipping service, together with other grades if needed.

As a 1.4513 plate supplier SHH STEEL also stocks and sources the wider range of stainless steel sheets and plates, so mixed orders of ferritic and austenitic sheet can travel in one container with one set of paperwork.

EN 10088-2 X2CrMoTi17-1 1.4513 is a titanium-stabilised 17 % chromium ferritic with about 1 % molybdenum, filling the gap between 1.4510 and 1.4521 for exhaust, appliance and trim work. Choosing it is the easy part. Getting genuine material that matches the certificate, in the gauge and finish your parts need and on a predictable schedule, is where a sourcing partner earns its place, and that is the work SHH STEEL does every day through long-term mill cooperation, consolidation and its own workshop.

The next step is simple. Send SHH STEEL your drawing, or an enquiry with the quantity, thickness, width, finish and delivery destination, and we will judge whether a direct mill contract or consolidation with processing fits your order better, and quote accordingly. Send your sizes and quantities for a quotation.
