Stainless Steel 310 contains 24–26% chromium, 19–22% nickel, and up to 0.25% carbon. The 310S grade lowers carbon to 0.08% or less, improving its welding capability. These alloys offer exceptional oxidation resistance up to 1100°C during continuous use and maintain strength at high temperatures. Mechanical properties include tensile strength around 520 MPa, yield strength around 205 MPa, and elongation of at least 40%. Their resistance to scaling, sulfidation, and thermal fatigue makes them ideal for high-temperature buttweld fittings.
