FIELD: metallurgy.
SUBSTANCE: invention relates to a method of making a part from a flat steel product containing 4–12 wt. % of manganese, preferably from more than 5 to less than 10 wt. % and possessing TRIP/TWIP-effect. Method consists in formation of flat steel product in part at first stage of deformation at temperature of flat steel product from 60 °C to below temperature Ac3, preferably 60–450 °C. Invention also relates to part produced according to specified method, and to use such parts.
EFFECT: technical result is improved degree of deformation of moulded part and reduced deformation forces.
