FIELD: metallurgy.
SUBSTANCE: iron-based powder sprayed with water, which is alloyed with 0.75-1.1 wt % of nickel, 0.75-1.1 wt % of molybdenum and up to 0.45 wt % of manganese contains 0.5-3.0 wt %, preferably 0.5-2.5 wt % and most preferably 0.5-2.0 wt % of copper and inevitable impurities. Alloyed powder composition based on iron contains iron-based powder sprayed with water, 0.4-0.9 wt %, preferably 0.5-0.9 wt % of graphite, lubricant and if required solid-phase materials improving machinability and flow characteristic. The obtained composition is pressed and sintered in a reducing or neutral atmosphere at atmospheric pressure or lower than that and temperature of more than 1000°C.
EFFECT: obtaining products with inconsiderable shrinkage at sintering, which have high mechanical properties.
