309s Stainless Steel 
 309s Stainless Steel 
 309S corresponding Chinese brands are 0Cr23Ni13, American Standard S30908 (U.S. AISI, ASTM) 



 Characteristics and uses: corrosion resistance, heat resistance than 0Cr19Ni9 good. 


 Features: The following can withstand repeated heating 980 ℃, high temperature strength and oxidation resistance, anti-carburizing properties. Usage: furnace materials. 309S: (0Cr23Ni13) features: The following can withstand repeated heating 980 ℃, high temperature strength and oxidation resistance, anti-carburizing properties. 



 Usage: furnace materials. 309S is cutting stainless steel containing sulfur, the main requirements for cutting and high tables Guanghao occasions. 309L is a low-carbon 309 stainless steel variant, for the need for welding applications. Lower carbon content makes it close to the weld heat affected zone to minimize carbide precipitation, and carbide precipitation may result in some environments, stainless steel intergranular corrosion (weld erosion).
