310 Stainless Steel
310 Stainless Steel is austenitic material used for high-temperature applications. The high chromium and nickel contents give the steel excellent oxidation resistance as well as high strength at high temperatures. This grade is also very ductile, and has good weldability enabling its widespread usage in many applications.
Grade 310S stainless steel is the low carbon version of Grade 310 and is suggested for applications where sensitization, and subsequent corrosion by high temperature gases or condensates during shutdown may become problem.
Grade 310 stainless steel is manufactured in accordance with ASTM A 167 and SX 310S to ASTM A 240.
