SS 310

SS 310

SS 310 (also known as AISI 310) is an austenitic stainless steel that is designed for high-temperature applications requiring superior oxidation resistance. It is widely used in industries where high heat and extreme conditions are present.SS 310 is a high-performance stainless steel alloy designed for high-temperature and oxidation-resistant applications. It is particularly suitable for industries such as furnace manufacturing, chemical processing, and aerospace, where extreme heat resistance and corrosion protection are crucial. SS 310S, a lower-carbon version, is ideal where weldability and resistance to sensitization are necessary
