Heat-resistant stainless steel sheet 0.5mm-80mm 0Cr23Ni13(309S)ASTM 309S/ ASTM A276 for boiler, industrial furnace
309 is a free cutting stainless steel containing sulfur for applications where free cutting and high surface finish are the main requirements.309 corresponding to the Chinese brand is 0Cr23Ni13, American standard S30908 (AISI, ASTM) characteristics and use: corrosion resistance, heat resistance is better than 0Cr19Ni9.For soldering applications.The lower carbon content minimizes carbides precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (welding erosion) in stainless steel in some environments.It can withstand repeated heating under 980 ℃, and has high high temperature strength, oxidation resistance and carburizing resistance.
