Common applications include industrial furnaces, annealing chambers, fused salt treatment installations and boiler parts, as well as heat exchangers.Alloy 310 stainless is an austenitic stainless steel with a high nickel and chromium content which makes the alloy heat resistant with excellent resistance to oxidation under mildly cyclic conditions through 2000ºF. 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 than the common austenitic alloys like alloy 304. Stainless alloy 310 is often used at cryogenic temperatures, with excellenttoughness to -450°F.
