Properties of 309S stainless Steel:
309 s corresponding Chinese brand is 0 cr23ni13, American standard S30908 (American AISI, ASTM) .corrosion resistance, heat resistance are better than 0 cr19ni9.309 s is containing sulfur free cutting stainless steel.
It is a variation of 309 stainless steel with lower carbon content. It is applied to the occasion. Low carbon content is made in the heat affected zone near the weld in the precipitation of carbide to a minimum,which may result in precipitation of carbide stainless steel inter-granular corrosion in some environments (welding erosion)
309S Generally used for furnace material, produced in 850 ℃ -- 1050 ℃ work of all kinds of heat-resistant artifacts, such as bracket, conveyor belts,annealing furnace cover, thermal cracking tubes, etc. Mainly used for free cutting and the surface which is bright and high clean demanding occasions.
