FIELD: powder metallurgy, possibly manufacture of constructional and wear resistant parts in building, machine engineering, mining, instrument making, processing and other industry branches. SUBSTANCE: method comprises steps of preparing charge, pressing it, sintering it in combination with infiltration; heat treatment of it. Novelty is non-uniform distribution of nickel and chrome with coefficient of concentration variation in range 0.17 - 0.37 during processes of preparing charge, pressing, sintering and heat treating. It is preferably to prepare polycomponent charge. Method allows to make steel of polycomponent charge with desired distribution of additives. EFFECT: significantly enhanced wear resistance, fatigue endurance of parts. 2 cl, 1 tbl
