Duplex 1.4462 belongs to the family of duplex stainless steels. This steel is characterised by its excellent combination of corrosion resistance, comparable to that of the austenitic grade 1.4404, and strength, about 150% higher than that of the 1.4404 austenitic grades. The use of duplex stainless steels, especially 1.4462 are gaining popularity due to their unique combination of excellent corrosion resistance, resistance to stress corrosion cracking and high tensile and yield strengths. As a result of its high strength, this steel is ideally suited to the constructional industry. The relatively lower nickel content, relative to the conventional austenitic grades, also makes 1.4462 an insteresting alternative from an economic point of view.
