310/S Stainless Steel Pipe and Tube

310/S Stainless Steel is an austenitic chromium nickel stainless steel with good oxidation resistance and strength at high temperatures. It resists oxidation in continuous service up to 2000ºF, as long as reducing sulphur gasses are not present. It also has a low coefficient of expansion, which prevents the steel from warping in high temperatures.  Grade 310/S has a lower carbon content than grade 310.
