ABSTRACT:
A source powder for a wear-resistant sintered material, consisting essentially of, in weight percentages, Cr: 3.0 to 6.0%, 2 Mo+W: 10.0 to 20.0%, V: 1.0 to 8.0%, Co: 10.0% or below, C: 0.20% to {0.01(2 Mo+W)+0.24 V}%, Si: 0.1 to 1.0%, Mn: 0.1 to 1.0% and the balance being Fe and unavoidable impurities, or one prepared by adding 0.10 to 0.8% of S to the above composition. This powder can be compacted into a green compact having a high green density, which can further give a wear-resistant sintered material having a high sintered density, hardness and strength.
