ASTM A240 SUS309S austenitic stainless steel plate Surface Finish

ASTM A240 SUS309S austenitic stainless steel plate is mainly used in high temperature environments. SUS309S austenitic stainless steel plate high chromium content and nickel content ensures good corrosion resistance and oxidation resistance. Compared with the 304 austenitic alloy, which at room temperature strength to be a little higher.
SUS309S austenitic stainless steel sheet typically exhibits good high-temperature strength, creep resistance and resistance to environmental corrosion. Therefore, they are widely used in industry, heat treatment furnace parts, such as: conveyor belts, rollers, stove, fire-resistant plate, pipe hangers and so on. These ratings also apply to the chemical processing industry, for carrying hot concentrated acid, ammonia and disulfide.
