  • Do you really know the story of 316 and 316L stainless steel ? ( 1 )
    Aug 16, 2018

    316L is widely used in chemical industry because of its excellent corrosion resistance. 316L is also a derivative of 18-8 type austenitic stainless steel with 2-3% Mo added. On the basis of 316L, a lot of steel grades were also derived, such as 316Ti was derived by adding a small amount of Ti, 316N was derived by adding a small amount of N, 317L was derived by increasing the content of Ni and Mo.

    Most of the existing 316L in the market is produced in accordance with American standards. For cost consideration, the steel plant generally limits the Ni content of the product as far as possible. According to the US standard, the Ni content of 316L is 10 to 14%, and the daily standard stipulates that the Ni content of 316L is 12 to 15%. According to the lowest standard, there is a 2% difference between American standard and Japanese standard in the content of Ni, reflected in the price is still very large, so customers still need to see when purchasing 316L products, products are referred to ASTM or JIS standards.

    The Mo content of 316L makes the steel possess excellent pitting resistance and can be safely applied in the environment containing Cl-isohalide ions. Because 316L is mainly used for its chemical properties, steel mills have a slightly lower requirement for surface inspection of 316L (relative to 304), and customers with higher surface requirements should strengthen surface inspection.
