Features of Processing of Corrosion Resistant Steels

The information about the applications and features of mechanical treatment of corrosion resistant steels which refer to the ferritic-austenitic class is provided in the paper. It is shown that increasing of alloying elements’ content, in comparison to austenitic steels, improves the strength characteristics while improving corrosion resistance and resulting in a dramatic reduction in machinability. The paper defines the directions of efficiency increase for machining of duplex steels by determining the processing conditions appropriate to reduce the tool wear intensity.
