ASTM 304 JIS SUS304 austenitic stainless heat resistant steel

ASTM 304 JIS SUS304 heat resistant steel high nickel chromium composition combines corrosion resistance and high temperature resistance (stable at ≤870 ℃), providing excellent ductility in the solid solution state, suitable for boiler components, heat exchangers, and high-temperature furnace internals.

During the processing of ASTM 304 JIS SUS304 austenitic stainless heat resistant steel, intergranular corrosion caused by carbide precipitation should be avoided. After welding, it is recommended to perform solution treatment or use low-carbon grade 304L. The quality assurance certificate (including grain size and mechanical properties) should be verified for the procurement of the plate.

Nickel price linkage pricing, ASTM 304 JIS SUS304 austenitic stainless steel bulk purchase reference price 14-20 yuan/kg, storage needs to be dry and ventilated to prevent stress corrosion cracking, priority should be given to ISO certified steel mills for direct supply channels.
