316S31（1.4401）是17%铬12%镍奥氏体不锈钢。总体耐腐蚀性能非常好，优于304不锈钢，但添加2%的钼也增强了在含氯化物和卤化物环境中的耐点蚀和缝隙腐蚀能力。有时被称为“船用级不锈钢”的316S31（1.4401）实际上对温暖的海水没有很好的抵抗力。
通常以退火状态供应，该牌号可通过轧制、冲压、拉拔和镦锻成型，任何热加工均在 1149-1260°C 之间进行。它也可以通过大多数标准焊接技术使用匹配的焊条连接。建议进行去应力退火以对抗冷加工后的内应力或恢复焊接后的耐腐蚀性。
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.
