What is 309S stainless steel?

The Chinese brand corresponding to 309S is 0Cr23Ni13, and 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 a lower carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may cause intergranular corrosion (weld erosion) of stainless steel in some environments.

It can withstand repeated heating below 980 ℃, and has high temperature strength, oxidation resistance and carburization resistance.
Widely used in boiler, energy (nuclear power, thermal power, fuel cell), industrial furnace, incinerator, heating furnace, chemical industry, petrochemical and other important fields.
