Stainless Steel - Duplex - 1.4462 (2205) Sheet and Plate
1.4462 (2205) Sheet and Plate Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.
1.4462 C max. 0.03 Cr 21.00 – 23.00 Ni 4.50 – 6.50 Mo 2.50 – 3.50 N 0.12 – 0.22 1.4462 belongs to the family of dulpex stainless steels. This steel is characterised by its excellent combination of corrosion resistance, comparable to that of the austenitic grade 1.4404, and
1.4462 belongs to the DUPLEX-family. This grade has a good resistance against pitting and stress corrosion cracking. Unique combination of corrosion resistance, resistance to stress corrosion cracking, high tensile and yield strength.
1.4462 (UNS S31803/ S32205 – F51 – SS2377) By using 1.4462 (UNS S31803/ S32205 – F51 – SS2377) you get a stainless duplex steel that has high resistance to various types of corrosion. It has good weldability and can be welded by several methods. The steel is widely used e.g. for propeller shafts, pump parts and piston rods.
