Stainless Steel 310, combining excellent high temperature properties with good weldability and ductility, is designed for high temperature service. SS 310 resists oxidation in continuous service at temperatures up to 1150°C provided reducing sulfur gases are not present. SS 310 is also used for intermittent service at temperatures up to 1040°C.
Stainless Steel 310S is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered “high temperature” service. The lower carbon content of SS 310S does reduce its high temperature strength compared to 310.
