904L-Rohrverschraubungen aus Edelstahl
904L stainless steel pipe fittings are high-alloy austenitic components designed for use in highly corrosive environments. Made from UNS N08904 (WNR 1.4539), these fittings offer excellent resistance to sulfuric acid, Chloride, and seawater corrosion. With high nickel (25%) and added copper content, 904L fittings are superior to conventional 316L and 317L grades in harsh chemical processing conditions. SASA FLANGE supplies a full range of 904L pipe fittings including elbows, T-Shirts, Reduzierstücke, Kappen, and stub ends, manufactured in accordance with ASTM A403 WP904L and ASME B16.9 Standards. These fittings are widely used in chemical plants, seawater systems, offshore oil platforms, and heat exchangers requiring long-term corrosion resistance and mechanical durability.
