Abstract
An iron-based powder for producing impact-resistant components 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-metallurgically producing impact-resistant steel components comprises using an iron-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 elements; compacting the powder into the desired shape; and sintering the compact.
