ASME SA182 F304 FORGED FLANGE SORF B16.5
Overview
Regarded to be the most basic stainless steel, the Stainless Steel 304 Flanges are also known as 18-8 grade with a higher content of chromium and low carbon content. The presence of low carbon content in the alloy restricts the formation of carbide precipitates during welding along with minimizing the 304 Stainless Flanges from being susceptible to intergranular corrosion.
Flanges made from alloy 304 is also known to resists moderately aggressive organic acids like acetic acid. The nickel present in the alloy is what provides resistance to the ASTM A182 Gr F304 Flange in moderately reducing solutions for e.g. in pure phosphoric acid, whatever the concentration, in cold solutions as well as up to 10% diluted hot solutions.
