304H stainless steel is an austenitic stainless steel alloy containing around 18–20% chromium and 8–11% nickel, with higher carbon content (0.04–0.10%) than the regular 304. This added carbon enhances strength and creep resistance at temperatures greater than 500°C. It has a tensile strength of around 585 MPa and a yield strength of around 240 MPa with high oxidation resistance and structural stability when subjected to thermal stress.
