Metal Injection molding (MIM) process is an advanced powder processing technique because of net shaping with shape complexity at low processing energy and 100% material utilization. This study has been performed to clarify and to optimize the relationship between the mechanical properties and the microstructures for the superhigh strengthening sintered low alloy steels (Fe–Ni system) by using MIM process. A 6 mass%Ni MIM steel showed excellent properties of 2000 MPa tensile strength, 5% elongation and 500 MPa fatigue strength. Instead of Fe–Ni, moreover, the Fe–Mn low alloy steel was investigated to obtain high performance properties, because Ni has a harmful influence upon the human body, for example, a Ni allergy.
