Metal injection molding (MIM) for DIN1.4091 heat and wear resistant stainless steel has been investigated, including the process steps of feedstock preparation, injection molding, debinding and sintering. The effects of sintering condition on the microstructure and mechanical properties of the sintered material have been investigated. The tensile strength and elongation of the sintered material from room temperature to 800 °C were measured. The developed MIM process has been applied to fabricate the key parts of turbochargers successfully.
