X2CrTi17 Ferritic Stainless Steel Plate & Coil Introduction
X2CrTi17 (1.4510) is a titanium-stabilized ferritic stainless steel with very low carbon content, providing excellent resistance to intergranular corrosion after welding. It combines good mechanical strength with moderate ductility and is supplied in the annealed condition for plate, coil and strip products. The titanium addition prevents sensitization during welding, making it suitable for fabrications that cannot be heat treated after welding. It is magnetic and offers good oxidation resistance up to about 800°C in intermittent service. Typical applications include household appliances, automotive exhaust systems, architectural trim and chemical equipment.

X2CrTi17 Ferritic Stainless Steel Plate & Coil Application Introduction
X2CrTi17 is selected where a combination of moderate corrosion resistance, weldability without post-weld heat treatment, and low cost is required. The titanium stabilization makes it immune to intergranular corrosion after welding. Typical applications fall into the following areas:
Product Applications: Dishwasher inner cabinets and spray arms, Cooker control panels and oven linings, Automotive exhaust mufflers and pipes, Architectural sandwich panels and flashings, Storage tanks for water, acetic acid, or food products, Decorative indoor and outdoor trim
Processed into products: Deep-drawn and formed parts such as tubs and bowls, Welded tubular components and exhaust pipe sections, Perforated strips and expanded metal, Brackets and supports in lightly corrosive environments, Heat exchanger plates (brazed or welded type)
Application industries: Domestic appliances (dishwashers, washing machines, ovens), Automotive (exhaust systems, catalytic converter shells, mufflers), Architecture and construction (cladding, roofing, decorative profiles), Chemical industry (tanks, piping for mildly corrosive fluids), Food and beverage processing (mild environment, non-severe corrosion exposure), Heat exchange (low-pressure water heaters, solar panels)
X2CrTi17 Ferritic Stainless Steel Plate & Coil Similar or Closely Related Substitute Materials
| Country/Region | Standard | Grade | Remarks |
|---|---|---|---|
| USA | ASTM A240/A240M | UNS S43940 (AISI 439) | Higher carbon (≤0.07%) but similar Cr and Ti stabilization; good alternative for many applications |
| Japan | JIS G4304/G4305 | SUS 436J1L | Nb-stabilized 17% Cr ferritic with slightly different composition; similar corrosion resistance |
| Europe | EN 10088-1 | X2CrMoTi17-1 (1.4513) | Mo-bearing variant with improved pitting resistance |
Notes:
Special considerations: Although titanium stabilized, X2CrTi17 can be susceptible to 475°C embrittlement if exposed for long periods in the temperature range 400–550°C. Ductile-to-brittle transition temperature is relatively high; therefore it is not recommended for cryogenic service or heavy impact loading at low temperatures. The material is magnetic and cannot be hardened by heat treatment. Surface pickling and passivation are recommended after welding to restore full corrosion resistance. Cold working increases strength but reduces ductility; post-cold-work annealing restores soft, formable condition.
