Stainless Steel 304H Pipes are made up of 18–20% chromium, 8–11% nickel, and a higher carbon content (0.04–0.10%) compared to standard 304. This extra carbon boosts high-temperature strength and creep resistance. Typically, these pipes show a tensile strength of about 585 MPa, a yield strength of 240 MPa, and an elongation of roughly 40%. The 304H grade is known for its excellent weldability, oxidation resistance, and structural integrity under thermal stress. These mechanical properties make it a great choice for applications that demand durability in continuous high-heat environments, like boilers, heat exchangers, and pressure vessels.
