Stainless Steel 904L Bars are made up of significant amounts of chromium, nickel, and molybdenum, along with copper that boosts their resistance to reducing acids. The typical composition features 20–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper, all while maintaining a low carbon content to avoid sensitization. On the mechanical side, 904L bars provide high tensile strength, remarkable toughness, and outstanding resistance to pitting and crevice corrosion. With an average yield strength of around 220 MPa and tensile strength surpassing 490 MPa, these bars are perfectly suited for extreme chemical and marine environments.
