Steel Strip Profiles
310S Stainless Steel Strip
310S stainless steel strip is engineered for extreme heat environments, offering superior oxidation and scaling resistance up to 1150°C. Its low carbon version prevents intergranular corrosion, making it ideal for welding and thermal process equipment. With robust mechanical strength and reliable surface finish, it is widely used in the petrochemical, power generation, and industrial heating sectors. A trusted choice for demanding high-temperature applications.
Product Introduction
310S stainless steel strip is a high-alloy austenitic stainless steel known for its excellent resistance to oxidation, corrosion, and high temperatures. Its composition includes high levels of chromium (24–26%) and nickel (19–22%), making it suitable for continuous service at temperatures up to 1150°C. 310S is a low-carbon version of 310, which minimizes carbide precipitation and is ideal for welding applications. It is widely used in furnace parts, heat treatment equipment, petrochemical plants, and thermal barrier systems.
