316L stainless steel plate
316L is a brand of stainless steel, AISI 316L is the corresponding American brand and Sus 316L is the corresponding Japanese brand. China's unified digital code is s31603, the standard brand is 022cr17ni12mo2 (new standard), and the old brand is 00Cr17Ni14Mo2, which indicates that it mainly contains Cr, Ni and Mo, and the number indicates the approximate percentage. The national standard is GB / T 20878-2007 (current edition).
3168-l stainless steel is widely used in chemical industry due to its excellent corrosion resistance of 3162-l derived elements. On the basis of 316L, many steel grades are also derived. For example, 316Ti is derived after adding a small amount of Ti, 316N is derived after adding a small amount of N, and 317L is derived by increasing the content of Ni and mo.
The Mo content of 316L makes the steel have excellent corrosion resistance and can be safely applied to the environment containing halogen ions such as Cl -. Since 316L is mainly used for its chemical properties, steel mills have slightly lower requirements for surface inspection of 316L (compared with 304), and customers with higher surface requirements should strengthen surface inspection.
