DUPLEX 1.4462

Duplex belongs to the group of stainless and acid resistant steels and is divided into five groups from lean duplex to hyper duplex. Characteristic of duplex steels is the balanced austenitic-ferritic two-phase structure (ratio 50:50), where the positive properties of ferrites and austenites are combined here. Duplex steels have high strength - comparable to higher-strength structural steels.

Due to their high chromium content compared to pure austenitic steels and the low nickel content at the same time, duplex steels are more stable compared to nickel-containing products. A high number of applications is given by the high corrosion resistance and excellent mechanical properties.
