316L is a stainless steel grades, said the main containing Cr, Ni, Mo digital percentage probably contains (not accurate, probably only), 316L is the material corresponding US label, Sus 316L is corresponding to the Japanese label. Standard of our country as 022Cr17Ni12Mo2. (new standard) of old brand 00Cr17Ni14Mo2

抗腐蚀性

Corrosion resistance

316L因其优异的耐腐蚀性在化工行业有着广泛的应用，316L也是属于18-8型奥氏体不锈钢的衍生钢种，添加有2～3%的Mo元素。在316L的基础上，也衍生出很多钢种，比如添加少量Ti后衍生出316Ti，添加少量N后衍生出316N，增加Ni、Mo含量衍生出317L。

316L because of its excellent corrosion resistance is widely used in chemical industry, 316L is belong to 18-8 type austenitic stainless steel are derived, add the Mo element 2 ~ 3%. On the basis of 316L, and derived a lot of steel, such as adding a small amount of Ti derived after 316Ti, add a small amount of N derived after 316N, increased Ni, Mo content derived 317L.

市场上现有的316L大部分是按照美标来生产的。出于成本考虑，钢厂一般把产品的Ni含量尽量往下限靠。美标规定，316L的Ni含量为10～14%，日标则规定，316L的Ni含量为12～15%。按最低标准，美标和日标在Ni含量上有2%的区别，体现到价格上还是相当巨大的，所以客户在选购316L产品时还是需要看清，产品是参照ASTM还是JIS标准。

The market of the existing 316L most is in accordance with the American Standard to production. Because of cost considerations, steel mills generally the Ni content of the products as much as possible to lower limit on. American standard regulation, Ni of 316L content for 10 ~ 14% day marks the regulation, Ni of 316L content for 12 ~ 15%. According to the minimum standard, American Standard and Japanese standard 2% of the difference in the Ni content, reflected in the price is quite huge, so customers in the purchase of 316L products still need to see, the product is according to ASTM or JIS standard.

Mo 316L content makes this kind of steel has excellent resistance to pitting corrosion, can be safely used in containing Cl - and halogen ion environment. As the main application of 316L is its chemical properties, surface inspection of steel on the requirements of 316L was slightly lower (relative to 304), higher on the surface of the customer must strengthen the surface inspection dynamics.
