316 stainless steel has advantages such as ultra-high temperature resistance, ultra-corrosion resistance, ultra-high strength, and ease of processing. What are the differences between 316 and 316L? 316L is widely used in the chemical industry due to its excellent corrosion resistance. It is also a derivative steel of 18-8 austenitic stainless steel, with 2-3% Mo added. On the basis of 316L, many steel grades have also been derived, such as adding a small amount of Ti to derive 316Ti, adding a small amount of N to derive 316N, and increasing Ni and Mo content to derive 317L. Most of the existing 316L in the market are produced according to American standards. Due to cost considerations, steel mills generally limit the Ni content of their products as low as possible. The American standard stipulates that the Ni content of 316L is 10-14%, while the Japanese standard stipulates that the Ni content of 316L is 12-15%. According to low standards, there is a 2% difference in Ni content between American and Japanese standards, which is reflected in the significant price. Therefore, when customers choose 316L products, they still need to see clearly whether the products refer to ASTM or JIS standards.
