Grade 304H has 18–20 % chromium and 8–11 % nickel content, with a higher content of carbon (0.04–0.10 %) for improving high-temperature strength. It provides tensile strength of 515–750 MPa, yield strength of approximately 205 MPa, and elongation of more than 40 %. The alloy possesses good ductility and corrosion resistance and resists deformation with constant heat exposure. Its higher content of carbon enhances creep and stress-rupture strength in service temperatures up to 700 °C.
