316L stainless steel is a low-carbon austenitic stainless steel with excellent corrosion resistance due to the addition of molybdenum (Mo) element. Compared with other stainless steel materials, 316L stainless steel exhibits extremely high corrosion resistance in chloride environments, and is particularly suitable for marine environments and chemical industries. In addition, 316L stainless steel is low-carbonized, not prone to intergranular corrosion, and has good oxidation resistance. These characteristics enable 316L stainless steel to maintain good mechanical properties and corrosion resistance even in high-temperature environments, making it suitable for high-temperature equipment and pipelines.
316L is widely used in the chemical industry due to its excellent corrosion resistance. 316L is also a derivative steel of 18-8 austenitic stainless steel, with 2-3% Mo added. Based on 316L, many steel grades are also derived, such as 316Ti derived by adding a small amount of Ti, 316N derived by adding a small amount of N, and 317L derived by increasing the Ni and Mo content.
Most of the existing 316L on the market are produced according to the American standard. For cost considerations, steel mills generally keep the Ni content of the product 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 the lowest standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is still quite huge in price, so customers still need to see clearly when purchasing 316L products, whether the product refers to ASTM or JIS standards.
The Mo content of 316L makes this steel have excellent corrosion resistance and can be safely used in environments containing halogen ions such as Cl-. Since 316L is mainly used for its chemical properties, steel mills have slightly lower surface inspection requirements for 316L (relative to 304), and customers with higher surface requirements should strengthen surface inspection efforts.

316L stainless steel has excellent corrosion resistance due to the addition of molybdenum (Mo) element, especially in chloride environment. It also has good oxidation resistance and intergranular corrosion resistance, suitable for high temperature environment and harsh chemical environment. In addition, 316L stainless steel is not prone to intergranular corrosion after low carbonization treatment, and can maintain good mechanical properties and corrosion resistance at high temperature.
Application fields
Chemical industry: 316L stainless steel is widely used in the production of fertilizers, petrochemicals, synthetic fibers, etc. due to its excellent acid and alkali resistance. It is used to manufacture corrosion-resistant pipes, containers, heat exchangers and other equipment.
Marine engineering: Due to its excellent seawater corrosion resistance, 316L stainless steel is used to manufacture key components of ships, structural parts and piping systems of offshore platforms to ensure the safety and reliability of marine facilities in harsh environments.
Food processing: 316L stainless steel is widely used in the manufacture of food processing equipment and containers such as agitators, conveyor belts, storage tanks, etc. due to its hygiene and corrosion resistance.
Other fields: It is also used in cookware, tableware, daily hardware, surgical instruments, major electrical appliances, industrial equipment, automobiles, aerospace and other fields.
Processing and maintenance
316L stainless steel cannot be strengthened by heat treatment, nor does it require post-weld annealing. It has excellent work hardening properties and is non-magnetic, making it suitable for manufacturing parts of various complex shapes.
