SUS347 Austenitic Stainless Steel

Introduction & Properties

SUS347 steel is a kind of austenitic stainless steel with element of niobium that can improve resistance to intergranular corrosion. It has the same level of corrosion resistance in the condition with acid, alkali and salt as well as that of SUS321, and SUS347 also has good  weldbility.
