904L is an austenitic, low-carbon stainless steel alloy characterized by excellent corrosion resistance, particularly in acidic conditions. Its composition has about 24% chromium, 19% nickel, 4.5% molybdenum, and traces of copper and manganese. This blend ensures excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. The material exhibits tensile strength about 490 MPa and yield strength of 220 MPa with good ductility and weldability. All these features make 904L forged fittings very suitable for high pressure and high temperature applications where durability and low maintenance are called for.
