The steel grade 1.4462 is a stainless acid resistant duplex steel with high strength and extremely good corrosion properties. Due to the duplex structure of the steel (austenitic-ferritic) and high contents of chrome and molybdenium it has very high resistance to pitting corrosion, crevice corrosion, uniform corrosion, corrosion fatigue and stress corrosion cracking.
Duplex stainless steel also referred to as an austenitic-ferritic steel, combine many of the beneficial properties of ferritic and austenitic steels. Due to its high content of chromium and nitrogen, and often also molybdenum, this steel offer good resistance to pitting and uniform corrosion. The duplex micro-structure contributes to their high strength and high resistance to stress corrosion cracking. Duplex steels also have good weldability.
