wilsonpipeline Pipe Industry Co., Limited is a leading manufacturer and supplier of nickel alloy and stainless steel products, including Super Duplex Stainless Steel Flanges, Stainless Steel Flanges, Stainless Steel Pipe Fittings, Stainless Steel Pipe. Stainless steel 310/310S is an austenitic heat resistant alloy having high resistance to oxidation under mildly cyclic conditions through 2000ºF.
This steel has a high nickel and chromium content that offers comparable corrosion resistance, high resistance to oxidation and retention of larger fraction of room temperature strength than the common austenitic alloys like Type 304. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450°F, and low magnetic permeability.
