ABSTRACT:
An alloy steel for use in injection-molded sinterings produced by powder metallurgy which comprises by weight, from 0.5 to 3% of Cr and/or Mn, from 0.3 to 1% of C, and balance Fe, is claimed.
The alloy steel according to the present invention provides injection-molded sinterings having favorable post workability well-comparable to that of Fe-Ni-C alloys, and further improved in abrasion resistance when hardened and tempered to give a high Vickers hardness of over Hv 700.
