Yaang is a stockholder and supplier of stainless steel grade 310 and 310S flanges, pipe, tube, pipe fittings, and fasteners including nuts, bolts, sockets, washers and more. 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.

Stainless steel 310S pipe fittings and other products are mainly manufactured in accordance with ASTM A167, while grade 310S fittings and other products are manufactured as per ASTM A240. 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 pipes, and stainless steel 310S flanges 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.
