Stainless Steel 304H Welded Pipes are made up of 18–20% chromium, 8–11% nickel, and a carbon content ranging from 0.04–0.10%, which significantly boosts their strength at high temperatures and creep resistance. They also contain manganese, silicon, and small amounts of phosphorus and sulfur. These pipes showcase impressive tensile strength of at least 515 MPa, yield strength of at least 205 MPa, elongation of at least 35%, and Brinell hardness reaching up to 201 HB. The higher carbon content makes 304H perfect for structural and pressure-bearing systems that operate in consistently high-heat environments.
