SX 310 Technical Data

Summary

SX 310 is a highly alloyed austenitic stainless steel 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.
SX 310S is the low carbon version of SX 310 and is suggested for applications where sensitisation, and subsequent corrosion by high temperature gases or condensates during shutdown may pose a  problem.
 

Typical Applications

SX 310/310S find wide application in all high-temperature environments where scaling and corrosion resistance, as well as high temperature strength and good creep resistance, are required.
