347 Stainless Steel Plate
347 Stainless Steel Plate is a stabilized austenitic stainless steel containing chromium, nickel, and minor additions of Niobium (Columbium) and Tantalum. This stabilization prevents intergranular corrosion by tying up carbon, making it immune to carbide precipitation when exposed to high temperatures (800℉ to 1500℉). It offers excellent high-temperature strength and oxidation resistance. 347 plate is the material of choice for welded heavy-gauge components operating in high-temperature service, such as boiler and pressure vessel parts, aircraft exhaust manifolds, and components for chemical processing plants.
