Description
Type 310S 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 310S forms a tenacious scale at high temperature and is resistant to spalling and performs better than Type 309 in thermal cycling applications.
Type 310S is the low carbon version of Type 310 and is utilized for ease of fabrication due to its better formability and weldability.
