    Description

    07Х17Н16 steel is used: for the production of hot-rolled and forged bars with diameter from 8 to 150 mm, used for the manufacture of parts, which have to meet the requirements of corrosion resistance and namagnichennosti.

    Note

    Free-cutting steel with high machinability, low magnetic susceptibility and high corrosion resistance.
