316L stainless steel is a derivative of 18-8 austenitic stainless steel, and its chemical composition is added with 2 to 3% Mo element. On the basis of 316L austenitic stainless steel, a variety of steel grades are derived. For example, 316Ti is derived by adding a small amount of Ti, 316N is derived by adding a small amount of N, and 317L is derived by adding Ni and Mo.

Most of the existing 316L grade steel coils on the market are produced according to American standards. The American standard stipulates that the Ni content of ASTM 316L stainless steel is 10-14%, while the Japanese standard stipulates that the Ni content of 316L stainless steel is 12-15%. According to the minimum standard, the Ni content of the American standard and the Japanese standard are 2% different, and the price is also very different. Therefore, when purchasing 316L stainless steel coils, it is necessary to see whether it refers to ASTM standards or JIS standards.
