A213 SA213 TP310S Stianless Steel Cold Drawn heat exchanger u tube
310S stainless steel is a highly alloyed austenitic stainless steel, mainly used for elevated temperature applications mainly due to the advantage of their oxidation resistance. Due to its high chromium and nickel content, the general corrosion resistance of 310S is more superior to 304 or 309 in most environments. 310 stainless steel is mostly similar to grade 309, but offers greater corrosion resistance and oxidation at high temperatures.
Stainless steel 310S seamless pipes and 310S fittings are widely used for manufacturing furnace components, oil burner parts, heat exchangers and piping systems in chemical plants. In addition, 310S seamless tubes are widely used for general piping requirements across various industry verticals.
