Alloy 310S is an austenitic chromium nickel stainless steel that posses good oxidation resistance and strength at high temperatures in continuous service up to 2000ºF (provided reducing sulfur gasses are not present). It is also used for intermittent service at temperatures up to 1900°F because it resists rescaling and has a low coefficient of expansion. This factor reduces the tendency of the steel to warp in heat service. Alloy 310S is similar to alloy 310 except for lower carbon content to minimize carbide precipitation during welding.
