Stainless Steel 1.4000
EN 1.4000
1.4000 (X6Cr13, SUS410S) is a low-carbon plain 13 % Cr stainless steel that stays essentially ferritic and non-hardenable, so it is used where basic corrosion resistance is combined with forming and welding rather than heat treatment.

What is 1.4000?
1.4000 (X6Cr13, SUS410S) is a low-carbon plain 13 % Cr stainless steel that stays essentially ferritic and non-hardenable, so it is used where basic corrosion resistance is combined with forming and welding rather than heat treatment. Typical annealed values are 285 MPa yield, 480 MPa tensile, 30 % elongation and 150 HB, with service to 700 °C; it is available as hot-rolled 1D plate, 2B/2D/2R cold-rolled sheet, +A and +AT-weld tube and +C/+SR bar. Corrosion resistance is limited to mild atmospheres and fresh water — it will rust in chlorides — and formability (score 65) is below 430 or 304. Move to 1.4016/430 for better corrosion resistance and appearance, or 1.4002/405 for welded pressure parts. 1.4000 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,480°C (2,696 °F). 1.4000 has a yield strength of 285 MPa (41.3 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 74% of stainless steel grades. Elongation at break is 30% and the elastic modulus is 220 GPa (31.9 Msi).

Working with 1.4000
Is 1.4000 easy to machine?
Machines like a soft low-alloy steel at roughly half of 1212 speed; use sharp positive-rake tooling, rigid setups and generous coolant to avoid the gummy built-up edge typical of low-carbon 13Cr.
Can 1.4000 be welded?
Readily welded by TIG/MIG/SMAW; use 309L or matching 410-type filler, preheat 100–200 °C on thick sections and consider a 700–760 °C post-weld anneal to restore HAZ ductility.
Can 1.4000 be formed, bent or molded?
Cold forms and deep draws reasonably well in the annealed condition (less than 430 or 304); allow generous bend radii (≥1t) and avoid heavy work near 400–500 °C to prevent embrittlement.
