Grade 310S Austenitic stainless steel

Grade 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 310S does reduce its high temperature strength compared to 310H.

Dual Certification

310S and 310H are often produced in "Dual Certified" form – mainly in plate and pipe. These items have chemical and mechanical properties complying with both 310H and 310S specifications. Product complying with 310 only or dual certified 310 and 310S may have a carbon content below 0.04% which will not be acceptable for some high temperature applications.

Typical Applications

Boiler Baffles, Furnace Components, Oil burner parts, Carburising boxes, Heat Treatment baskets and jigs, Heat exchangers, Welding filler wire and electrodes.
