ASTM A182 F304 Stainless Steel Flanges represent a widely utilized option among austenitic stainless-steel grades. These flanges feature a chromium content ranging from 15% to 20% and a nickel content between 2% and 10.5%, constituting the primary non-iron elements. Notably, SS 304L Slip on Flanges exhibit lower electrical and thermal conductivity compared to carbon steel counterparts, and they possess a non-magnetic nature. Their superior corrosion resistance facilitates easy shaping into diverse configurations. Additionally, ASTM A182 specifies standards for Forged or Rolled Alloy and Stainless-Steel Pipe Flanges, Fittings, Valves, and Parts, intended for high-temperature applications. It accommodates variations such as 304H and 304L, differing primarily in carbon content.
