316L steel plate is widely used in the chemical industry because of its excellent corrosion resistance. 316L is also a derivative of 18-8 austenitic stainless steel, with 2 to 3% Mo added. On the basis of 316L, many steel types 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 Ni and Mo content.
Most of the existing 316L on the market is produced in accordance with American standards. Due to cost considerations, steel mills generally limit the Ni content of products as low as possible. The American standard stipulates that the Ni content of 316L is 10 to 14%, and the Japanese standard stipulates that the Ni content of 316L is 12 to 15%. According to the minimum standard, there is a difference of 2% in the Ni content between the American standard and the Japanese standard. The price is still quite huge, so customers still need to see clearly when purchasing 316L products. Whether the products refer to ASTM or JIS standards.
The 316L Mo content makes this steel have excellent resistance to pitting corrosion and can be safely used in environments containing Cl- and other halogen ions. Because the main application of 316L is its chemical properties, steel manufacturers have slightly lower requirements for surface inspection of 316L (relative to 304), and customers with higher surface requirements need to strengthen the surface inspection.
