PURPOSE:To obtain low alloy iron powder for sintering having superior hardenability and compactibility at a reduced cost of starting materials by specifying a composition consisting of Mo, C, O, Si, Cr, Cu, Ni and Fe. CONSTITUTION:This low alloy iron powder for sintering consists of, by weight, 0.2-2.0% Mo, <=0.05% C, <=0.2% O, <=0.2% in total of Si, Cr, Cu and Ni, and the balance Fe with inevitable impurities, and it is simply obtd. by a water spraying method by which water is sprayed under high pressure on a molten alloy having said composition allowed to flow out of a tundish. The powder has superior hardenability and compactibility and is suitable for use as a material for a high density and high strength sintered material for structural machine parts.
