A182 F304L stainless steel flange include chromium, nickel, manganese, silicon and other elements. Among them, chromium accounts for a relatively high proportion, accounting for 18% to 20% of the total amount of stainless steel. Chromium can react with oxygen to form a dense oxide film, which plays an anti-corrosion role.
The hardness of A182 F304L flange is generally 85-90HB, the yield strength is Greater than or equal to 205MPa, the tensile strength is Greater than or equal to 515MPa, and the elongation is Greater than or equal to 30%. Its performance is closely related to its chemical composition, especially the content of molybdenum, titanium, niobium and other elements.
The characteristics of F304 stainless steel flange mainly include good corrosion resistance, high temperature resistance, wear resistance and toughness. In addition, A182 F304L stainless steel flange also has good weldability, processability and easy cleaning.
