SUS316L stainless steels

SUS316L is a stainless steel grade, SUS316L is the corresponding Japanese designation. my country's unified digital code is S31603, the standard grade is 022Cr17Ni12Mo2 (new standard) (new standard), and the old grade is 00Cr17Ni14Mo2, indicating that it mainly contains Cr, Ni, Mo, and the number indicates the approximate percentage.

SUS316L is widely used in the chemical industry because of its excellent corrosion resistance. SUS316L is also a derivative steel type of 18-8 austenitic stainless steel with 2 to 3% Mo element added. On the basis of SUS316L, many steel grades are 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.
