There is a growing need in the PM industry for materials with reduced or no Cu or Ni and also lesser total alloying elements to minimize costs. Towards this end, a variety of research activities have been undertaken and this manuscript is a report on Cu-free and Nickel-free steels that have been developed. The combination of Mn with a moderate level of Mo results in PM steel alloys with mechanical properties approaching and/or surpassing those of the diffusion alloy FD-0405. Equally important, these alloys can be processed under typical, industrial sintering conditions. With accelerated cooling, these manganese steels can be used as lean alloy, sinter-hardening grades. The benefits of ferrous PM alloys containing manganese are discussed.
