PURPOSE: To produce a sintered compact improved in wear resistance, etc., by C, having a high green density and high sintered density and especially without its toughness being lowered due to segregation of C.

CONSTITUTION: The powder of a 13%-Cr SUS (Stainless steel) having ≤ about 149μm particle diameter produced by gas atomization and fine CB powder having 10-40mmμ particle diameter and having 40-300ml/100g oil absorption are mixed respectively in a specified amt., 1wt.% of zinc stearate is added as a binder, and the mixture is charged into a bladed mixing agitator and sufficiently agitated. The surface of the SUS powder after being agitated is covered almost uniformly with the fine CB powder. The powder is compacted and sintered to obtain a sintered compact excellent in compact density and sintered density and without any C segregation.
