Asiaalloy 310 (UNS S31000) is an austenitic stainless steel is used in high temperature corrosion resistant applications. The alloy resists oxidation up to 1100°C (2010°F) under mildly cyclic conditio
Type 310 is a high temperature chromium nickel austenitic stainless steel with high creep strength that resists oxidation at temperatures up to 2000˚F in dry air. Type 310 forms a tenacious scale at high temperature and is resistant to spalling and performs better than Type 309 in thermal cycling applications. Type 310 has good sulfidation resistance and good resistance to carburization in moderately carburizing atmospheres. Type 310 is non-magnetic in the annealed and cold worked conditions and is as resistant to corrosion as Type 304/304L.
