Duplex alloy EN 1.4462 / 03X22Н5AM2

Steel 1.4462 / 03Х22Н5АМ2 

1.4462 austenitic steel has the highest strength and resistance to corrosion processes, which largely determines the scope of its application. The design of this alloy is characterized by resistance to wear and almost are not amenable to General, crevice or pitting corrosion. Features High-quality stainless steel of grade 1.4462 is a ferritic-austenitic alloy. It features excellent weldability by all types of welding, improved almost twice the strength in comparison with analogues (SAF 304 and 316). The latter feature has allowed to reduce the weight of structures without compromising their reliability by 50%. Stainless steel of this type shows up in corrosive environments, its resistance is comparable to high-alloyed alloys of type 6Мо. Purpose and scope Such alloys find wide application in industrial production. Of them are manufactured pressure vessels, transport pipelines, vessels for storage of reactive substances, heat exchangers, pipelines for the chemical industry, elements of oil and gas drilling rigs. Heavy metallurgy, mining, petrochemical industry, medicine and food industry is only a small part of consumers of alloy steel 1.4462. On all questions of purchase please contact us on the site.
