Abstract SU 1741459 A1

FIELD: metallurgy. SUBSTANCE: steel further contains phosphor and nitrogen with the following ratio of components, % by weight : carbon 0.02- 0.07; manganese 0.15-0.30; copper 0.02-0.30; aluminum 0.03-0.07; boron 0.0005-0.005; phosphor 0.04-0.10; nitrogen 0.001-0.007; iron the balance. Introduction of steel allows usage of metal in production of cars to be reduced by decreasing thickness of car parts. EFFECT: increased efficiency, enhanced reliability in operation and high service life. 3 tbl
