Home > Pipe Fittings > Stainless Steel 904L Pipe Fittings
Stainless Steel 904L Pipe Fittings are top-notch, corrosion-resistant components designed to connect different sections of piping in systems that demand exceptional durability and chemical resistance. Made from 904L stainless steel, which is a low-carbon austenitic alloy, these fittings are built to hold up in tough environments where regular stainless steels might falter. Their remarkable resistance to strong acids, chloride attack, and stress corrosion cracking makes them perfect for industries with high demands. With a blend of strength, weldability, and long-lasting performance, Stainless Steel 904L pipe fittings guarantee leak-proof, corrosion-resistant connections in critical fluid handling systems.
The chemical makeup of Stainless Steel 904L features 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper, all while keeping carbon content very low. This unique combination offers outstanding resistance to pitting and crevice corrosion, especially in acidic and chloride-rich environments. On the mechanical side, 904L boasts a tensile strength of about 490 MPa, a yield strength of 220 MPa, and an elongation of roughly 35%, providing good ductility and strength under pressure. These characteristics, along with its excellent weldability, make 904L a go-to choice for applications involving corrosive chemicals and high-temperature fluid flow.
