Chromium (19–23%), nickel (23–28%), molybdenum (4–5%), copper (1–2%), and low carbon content (≤0.02%) make up stainless steel 904L seamless pipes. This austenitic stainless steel has exceptional resistance to pitting, corrosion from chloride stress, and strong reducing acids. Mechanical characteristics include an approximate elongation of 35%, a yield strength of 220 MPa, and a tensile strength of 490 MPa. In critical industrial applications, its seamless construction guarantees leak-proof performance under high pressure and extreme temperature conditions, while its high nickel and molybdenum content increases its durability and resistance to corrosion.
