310 Stainless Steel
UNS S31008 | ASTM A240 | ASTM A276/A479 | AMS 5521 | AMS 5651 |ASME SA-240/SA-479310 Stainless Steel
310 provides good malleability and weldability with superb high temperature properties. Because of these superb high temperature properties, 310 is often used in furnace parts, oil burner parts, carburizing boxes, heat treatment baskets and jigs, heat exchangers and welding filler wire and electrodes. Even though it is not typically used in cryogenic environments, it remains exceedingly tough in cryogenic temperatures. On the Rockwell B hardness scale, 310 has a hardness of 95. 310 provides excellent resistance to corrosion because of its high chromium content.
Common industry/applications are: Flare tips, Tube hangers for petroleum refining and steam boilers, Coal gasifier internal components, Food processing equipment, Refractory anchor bolts, Burners, and combustion chambers
Product forms include Reducers, Flanges, Pipe, Plate, Round Bar, Sheet, and Tubing.
