316L Stainless Steel Properties And Uses

316L stainless steel properties and uses

Due to its excellent corrosion resistance, 316L stainless steel has a wide range of applications in the chemical industry. 316L is also a derivative of 18-8 type austenitic stainless steel with 2-3% Mo added. Many steel grades are also derived based on 316L. 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 316Ls on the market are manufactured according to the American Standard. For cost reasons, steel mills usually try to reduce the Ni content of their products to a lower limit. 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 the minimum standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is quite large in price, so when purchasing a 316L product, make sure that the product refers to it clearly. need to do it. Compliant with ASTM or JIS standards.

With a Mo content of 316L, this steel has excellent pitting corrosion resistance and can be safely used in environments containing Cl- and other halogen ions. Since 316L is used primarily due to its chemical nature, steel mills have slightly lower 316L surface inspection requirements (compared to 304), and customers with higher surface requirements need to enhance surface inspection.

Use of 316L stainless steel: seawater, chemicals, dyes, paper, oxalic acid, fertilizers, and other production equipment; photo, food industry, coastal facilities, ropes, CD rods, bolts, and nuts.
