奧氏體不銹鋼

316S31（1.4401）是17%鉻12%鎳奧氏體不銹鋼?？傮w耐腐蝕性能非常好，優(yōu)于304不銹鋼，但添加2%的鉬也增強(qiáng)了在含氯化物和鹵化物環(huán)境中的耐點蝕和縫隙腐蝕能力。有時被稱為“船用級不銹鋼”的316S31（1.4401）實際上對溫暖的海水沒有很好的抵抗力。

通常以退火狀態(tài)供應(yīng)，該牌號可通過軋制、沖壓、拉拔和鐓鍛成型，任何熱加工均在 1149-1260°C 之間進(jìn)行。它也可以通過大多數(shù)標(biāo)準(zhǔn)焊接技術(shù)使用匹配的焊條連接。建議進(jìn)行去應(yīng)力退火以對抗冷加工后的內(nèi)應(yīng)力或恢復(fù)焊接后的耐腐蝕性。

316S31 (1.4401) is 17% chromium 12% nickel austenitic stainless steel. The overall corrosion resistance is very good, superior to 304 stainless steel, but the addition of 2% molybdenum also enhances the resistance to pitting and crevice corrosion in chloride and halide containing environments. 316S31 (1.4401), sometimes called "marine grade stainless steel", is actually not very resistant to warm sea water.

Usually supplied in annealed state, the grade can be formed by rolling, stamping, drawing and upsetting, and any hot working is carried out between 1149-1260 ° C. It can also be connected by most standard welding techniques using matching electrodes. Stress relief annealing is recommended to resist internal stress after cold working or restore corrosion resistance after welding.
