Stainless Steel 310S Seamless Pipes & Tubes
SS 310S (UNS S31008) is a high-chromium, high-nickel austenitic stainless steel designed for outstanding high-temperature oxidation resistance. With 25% Cr and 20% Ni, it maintains strength and resists scaling up to 1150C, making it ideal for furnace and heat treatment applications.
