309S Stainless Steel

Detail

309S stainless steel is a variant of 309 stainless steel with a lower carbon content and is used where welding is required. Features: It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburization resistance. Widely used in boilers, energy (nuclear power, thermal power, fuel cells), industrial furnaces, incinerators, heating furnaces, chemical, petrochemical and other important fields.
