Summary
SX 310 is a highly alloyed austenitic stainless steel designed for high-temperature applications. Its high chromium and nickel content provides excellent oxidation resistance and high strength at elevated temperatures. Additionally, this grade exhibits good ductility and weldability, making it widely used in various industries.
SX 310S is the low-carbon version of SX 310, recommended for applications where sensitization and subsequent corrosion by high-temperature gases or condensates during shutdown may be a concern.
Typical Applications
SX 310 / 310S is widely used in all high-temperature environments, where scaling and corrosion resistance, high-temperature strength, and creep resistance are required.
