Product Name: 904L stainless steel hot-rolled coil
Brief Introduction: 904L is a high-alloy super austenitic stainless steel with core components of 20% chromium, 25% nickel, 4.5% molybdenum, and 1.5% copper. Its resistance to pitting and stress corrosion in highly corrosive environments, such as dilute sulfuric acid and seawater, far surpasses that of 316L. It has a tensile strength ≥490MPa and an elongation ≥35%.
