ABSTRACT:
A steel powder consisting of a combination of purified steel and prealloyed manganese, chromium, molybdenum and nickel. The steel powder is used in the production of metal parts using powder metallurgy. The addition of the prealloyed elements results in a metal part having greater strength and hardness with a low oxygen content and good compressibility.
