Stainless Steel 904L Bars are composed of Nickel (23–28%), Chromium (19–23%), Molybdenum (4–5%), and Copper (1–2%), featuring a very low carbon content (<0.02%) to avoid intergranular corrosion. This distinctive composition offers remarkable resistance to sulfuric and phosphoric acids. The bars boast a tensile strength of around 490 MPa and a yield strength of about 220 MPa, along with impressive elongation and toughness. They also exhibit excellent mechanical stability, weldability, and impact resistance, making them perfect for high-temperature and corrosive environments.
