FIELD: metallurgy.
SUBSTANCE: water-sprayed previously alloyed steel powder contains the following components, in wt %: 0.4-2.0 Cr, 0.1-0.8 Mn, less than 0.1 V, less than 0.1 Mo, less than 0.1 Ni, less than 0.2 Cu, less than 0.1 C, less than 0.25 O, less than 0.5 unavoidable admixtures, balance - iron. The powder composition on the basis of the iron comprises a steel powder mixed with 0.35-1 wt % of graphite, 0.05-2 wt % of lubricant materials, and optionally, copper in the amount of up to 3%, and solid phase materials, and agents that improve treatability. A sintered item having perlite/ferrite microstructure is produced by means of pressing of a powder composition under the pressure of 400-2000 MPa, sintering in the reducing atmosphere at the temperature making 1000-1400°C and if required, forging of the heated item at the temperature making more than 500°C or thermal processing, or tempering of the produced item.
EFFECT: item has high ultimate strength, yield strength, extension and hardness.
