Stainless Steel 904L Coils are low-carbon, high-alloy austenitic stainless steels that contain 19-23% chromium, 23-28% nickel, 4-5% molybdenum, along with trace amounts of copper and manganese. This distinctive composition offers remarkable resistance to strong reducing acids like sulfuric acid and prevents chloride-induced pitting. The mechanical properties include a tensile strength ranging from 490-710 MPa, a minimum yield strength of 220 MPa, an elongation of 35%, and a hardness between 140-190 HB. The exceptional metallurgical stability and toughness of SS 904L make it perfect for highly corrosive environments, ensuring reliability and a long service life.
