An iron-based powder for producing impact-resistant compo- nents by powder compacting and sintering contains, in addition to Fe, 0.3-0.7 % by weight of P, 0.3-3.5 % by weight of Mo, and not more than 2 by weight of other alloying elements. A method of powder-metatlurgicalty producing impact-resistant steel components comprises using an ir- on-based powder which, in addition to Fe, contains 0.3-0.7 % by weight of P, preferably 0.35-0.65 % by weight of P, 0.3-3.5 % by weight of Mo, preferably 0.5-2.5 % by weight of Mo, and not more than 2 % by weight, preferably not more than 1 by weight, of other alloying ele- ments; compacting the powder into the desired shape; and sintering the compact.
