Description
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.
