High nitrogen and nickel-free 0Cr17Mn11Mo3N stainless steels were prepared using gas-atomized Fe-17Cr-11Mn-3Mo alloy powders by metal injection molding (MIM) technique, and optimized debinding and sintering process were studied. The results show that 60wt% of the binder can be extracted from injection-molded green bodies by solvent debinding, and almost all the binder is removed after reasonable thermal debinding. The sintering prameters have significant effect on the relative density and the nitrogen content of sintered specimens, and the optimal sintering conditions are determined to be 1300°C, 2h in flowing nitrogen atmosphere, under which a favorable combination of the relative density of 99.1% and the nitrogen content of 0.78wt% can be obtained. The yield strength, ultimate tensile strength and hardness of 0Cr17Mn11Mo3N stainless steels made by MIM can be as high as 580MPa, 885MPa and 227HV respectively, which are much higher than those of MIM 316L stainless steel.
