SS 310S is a high chromium (25%) and nickel (20%) austenitic stainless steel designed specifically for maximum resistance to oxidation and high-temperature corrosion. Retains good strength up to 1100°C. Used wherever standard 304 and 316 grades fail due to excessive temperature — furnace components, kilns, incinerators, and heat treatment equipment.
