410 stainless steel (UNS S41000) is a basic martensitic stainless steel containing 11.5–13.5% chromium and a relatively high carbon content (≤0.15%). Unlike austenitic grades (like 304), 410 can be hardened by heat treatment (quenching and tempering) to achieve high strength and hardness. It offers good corrosion resistance in mild environments and is widely used for cutlery, valves, pump shafts, and fasteners. It is designated as 12Cr13 (GB/T, China), SUS410 (JIS, Japan), and 1.4006 (EN, Europe).
Chemical Composition
Typical chemical composition (% by mass) per ASTM A240 / EN 10088.
| Grade | C (%) | Cr (%) | Mn (%) | Si (%) | Type |
|---|---|---|---|---|---|
| 410 / S41000 | ≤0.15 | 11.5–13.5 | ≤1.00 | ≤1.00 | Martensitic |
Note: 410 is a martensitic grade. It does not contain nickel (Ni), making it a cost-effective option. The higher carbon content allows it to be hardened through heat treatment.
