The powder metallurgy route may allow sintered manganese steels to be made based on pure iron powder and ferromanganese powder with control over alloy microstructure. The factors that contribute to the mechanical properties of sintered Fe-3%Mn-0,8%C manganese steel, such as the sintering atmosphere, dew point, sintering temperature, cooling rate are summarized. The paper shows the influence of these parameters on the tensile strength, yield strength, transverse rupture strength, impact strength and hardness. It showed that tensile high strength level higher then those of many present sintered steels can be obtained already in the as-sintered condition.
