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.
