How much temperature can 309S stainless steel seamless pipe withstand? The 309S seamless stainless steel pipe can withstand repeated heating below 980oC and has high temperature resistance, oxidation resistance and carburization resistance. You know? 309S is a free-cut stainless steel containing sulfur, which is sometimes used on occasions that require mainly free cutting and high surface finish.
The Chinese brand corresponding to 309S is 0Cr23Ni13, and the American standard S30908 (American AISI, ASTM) features and uses: corrosion resistance and heat resistance are better than 0Cr19Ni9.
309s is a variant of 309 stainless steel with lower carbon content and is used where welding is required. Lower carbon content minimizes carbide precipitation in the heat-affected area near welding, and carbide precipitation can cause stainless steel to cause intergranular corrosion (welding erosion) in certain environments.
