Manufactured from a high-alloy, low-carbon austenitic stainless steel, Stainless Steel 904L Buttweld Fittings contain elevated levels of nickel, chromium, molybdenum, and copper. This unique composition offers remarkable resistance to reducing acids like sulfuric and phosphoric acid, along with excellent protection against pitting and crevice corrosion in chloride-rich environments. The low carbon content reduces the risk of intergranular corrosion post-welding, while the alloy maintains impressive tensile strength, ductility, and stability at both ambient and elevated temperatures.
