Abstract (en)

A method of manufacturing an alloy part comprises mixing an alloy powder and a binder, the alloy powder having a composition including 40 to 50wt% Cr, 1 to 2.5wt% Si, 0.5wt% or less C, 5.6 to 6.2wt% B and the remainder Fe and unavoidable impurities; performing an injection molding on the mixture to form the injection moldings to have a shape of the part;removing the binder from the injection moldings; and sintering the injection moldings from which the binder is removed.
