309S 2B Stainless Cold Rolled Coils
Product Description
309S 2B Stainless Cold Rolled Coils: Cold Rolled Commonly used in the steel industry, different from hot-rolled coils. It refers to the steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a full coil with a winder. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and a higher finish, but produce more internal stress, and are often annealed after cold-rolling.
309S stainless steel is a free cutting stainless steel containing sulfur, used for the main requirements of free cutting and high surface finish. 309S corresponding Chinese brand is 0Cr23Ni13, American standard S30908(American AISI, ASTM) characteristics and uses: corrosion resistance, heat resistance are better than 0Cr19Ni9. The 309s is a variant of the lower carbon 309 stainless steel for use where welding is required. The lower carbon content minimizes the carbide precipitation in the heat-affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments. It can withstand repeated heating below 980 ℃, and has high high temperature strength, oxidation resistance and carburizing resistance. Widely used in boiler, energy (nuclear power, thermal power, fuel cell), industrial furnace, incinerator, heating furnace, chemical industry, petrochemical and other important fields.
