Weight(KG/PC)=thickness(mm) x width(Meter) x length(Meter) x 7.98
Small knowledge for 309/309S stainless steel
The corresponding 309S China brand is 0Cr23Ni13, American Standard S30908 (AISI, ASTM) properties and uses: corrosion resistance and heat resistance are better than 0Cr19Ni9. 309 compared with 309S, no sulfur content of S.
309S is a variant of the 309 stainless steel with low carbon content, used for welding. The lower carbon content reduces the amount of carbides precipitated in the heat affected zone near the weld, and the precipitation of carbides may lead to intergranular corrosion (corrosion) of stainless steel in some environments.
