AISI | ISO | SUS (JIS) | DIN | Description |
---|---|---|---|---|
Stainless steels | ||||
302 HQ | A2 | XM-7 | 1.4567 | Austenitic chromium-nickel steel, highly resistant to corrosion. Due to the additional copper content, it is particularly suitable for cold forming. |
304 | A2 | 304 | 1.4301 | Austenitic chromium-nickel steel, highly resistant to corrosion. |
316 | A4 | 316 | 1.4401 | Particularly corrosion-resistant austenitic chromium-nickel steel with molybdenum content. |
316 Cu | A4 | 316 Cu | Similar to 316, with additional copper content to improve cold formability. | |
316 L | A4 | 316 L | 1.4404 | Particularly corrosion-resistant austenitic chromium-nickel steel with molybdenum content and with lower carbon content compared to conventional 316. |
410 | C1 | 410 | 1.4006 | Heat-treatable, martensitic stainless steel. Polished against water and steam-resistant. |
430 | F1 | 430 | 1.4016 | Ferritic chromium-nickel steel, mirror polishing, resistant to water, steam, weak acids. |
