Stainless Steel 347 Valves

Stainless Steel 347 is one of the stabilized austenitic stainless steel that offers good resistance to intergranular corrosion and used for high temperature. This is due to columbium (niobium) that is added in the alloy helps in pinning the carbon to prevent the formation of carbides hence improves the corrosion and oxidation properties at high temperatures. Stainless Steel 347 valves are used in several processes where high strength and stability of the working conditions are needed.
