Abstract
A material which can be used to manufacture components which exhibit high strength and high wear resistance, at the same time possessing reasonable ductility. The material also has cost advantages compared to other potential metal powder solutions. An iron based powder composition which achieves desired microstructure/properties and associated sliding wear resistance with reduced content of expensive alloying ingredients such as admixed elemental Ni and Copper.
