The chemical composition of steel production standards (chemical composition of steel strip compliance requirements of not less than 10 of nickel, not less than 2 mo, not less than 16 chromium, carbon is less than or equal to 0.08), if there are people return or claim, all losses themselves.
Q:What steelmaking furnace for stainless steel bars?
