310S Stainless Steel Tube ASTM A213 ASME SA213 310S 310H Stainless Steel Tubes

Guanyu Steel Tube is specialized manufacturer of 310S Stainless Steel Tube in China. 310S Stainless steel Tubes is a combination of good strength and corrosion resistance in temperature up to 2100°F (1149°C). Due to its relatively high chromium and nickel content it is superior in most environments to 304 or 309 stainless.  ASTM A213 / ASME SA 213 310S 310H Stainless Steel Tube is typically used for elevated temperature applications.

Its high chromium and nickel content provides comparable corrosion resistance, superior in oxidation resistance, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304. 310S Stainless Steel Tube is an austenitic heat resisting alloy with excellent resistance to oxidation under mildly cyclic conditions to 2100°F. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength.

310S Stainless Steel is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the steel excellent oxidation resistance as well as high strength at high temperature. This grade is also very ductile, and has good weldability enabling its widespread usage in many applications.

Typical Applications Grade 310/310S is used in fluidised bed combustors, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, Stainless Steel Reheater Tubes and Superheater Tubes for Boiler, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures.

310S Stainless Steel combining excellent high temperature properties with good weldability and ductility, is designed for high temperature service. 310S stainless steel resists oxidation in continuous service at temperatures up to 1150°C provided reducing sulfur gases are not present. 310S is also used for intermittent service at temperatures up to 1040°C.
