Materials overview of Stainless Steel Bolts and Nuts

AISI ISO SUS (JIS) DIN Description
302 HQ A2 XM-7 1.4567 Austenitic chromium-nickel steel, profoundly safe to corrosion. Due to the extra copper substance, it is especially appropriate for cold shaping.
304 A2 304 1.4301 Austenitic chromium-nickel steel, profoundly safe to corrosion.
316 A4 316 1.4401 Particularly corrosion-resistant austenitic chromium-nickel steel with molybdenum content.
316 Cu A4 316 Cu Especially corrosion-resistant austenitic chromium-nickel steel with molybdenum substance.
316 L A4 316 L 1.4404 Especially corrosion-resistant austenitic chromium-nickel steel with molybdenum substance and with lower carbon substance compared to conventional 316.
410 C1 410 1.4006 Heat-treatable, martensitic stainless steel. Cleaned against water and steam resistant.
430 F1 430 1.4016 Ferritic chromium-nickel steel, reflect cleaning, resistant to water, steam, weak acids.
