<p>The present invention provides iron based metallurgical powder compositions and a method of making and using the same. The metallurgical powder compositions of the present invention contain certain amounts of an iron alloy powder having iron and at least one alloying additive; substantially pure iron powder; and a carbon powder, such as graphite. The metallurgical powder compositions are prepared by admixing the iron alloy powder with the iron powder and carbon powder. The metallurgical powder compositions thus produce and when formed into metal parts have, for example, improved machinability properties.</p> |
