Characteristics: Corrosion resistance: S31688 stainless steel has excellent corrosion resistance, and has high corrosion resistance in acidic, alkaline and chloride environments. It is particularly suitable for applications where corrosion resistance is critical, such as chemical, marine and food processing.

Good weldability: S31688 stainless steel has good welding properties and can be connected by conventional welding methods. However, when welding, it is necessary to pay attention to the selection of appropriate welding materials and reasonable welding processes to avoid intergranular corrosion at the welded joints.

Resistance to chloride stress corrosion cracking: Due to its high molybdenum content, S31688 stainless steel exhibits good resistance to stress corrosion cracking in chloride environments.

A common heat treatment method for S31688 stainless steel is solution annealing, which is heated in a temperature range of about 1020-1100 and then cooled quickly to improve the corrosion resistance of the material.

S31688 stainless steel is used in a wide variety of applications, including chemical, pharmaceutical, food processing, medical devices, and aerospace. S31688 is used in these applications in equipment and components that require corrosion resistance and high temperature resistance, such as containers, pipes, valves, heat exchangers, trays, medical devices, etc.
