Title: HEAT-RESISTANT SINTERED MATERIAL HAVING EXCELLENT HIGH-TEMPERATURE WEAR RESISTANCE AND SALT DAMAGE RESISTANCE AND METHOD FOR PRODUCING SAME
Abstract:
Provided is a heat-resistant sintered material: that has a composition which includes, by mass%, Cr: 15 to 30%, Ni: 8 to 30%, Si: 2.0 to 6.0%, C: 0.5 to 2.5%, and the balance comprising Fe and inevitable impurities; and that has a structure in which a hard phase is dispersed in a parent phase. The parent phase contains Fe, Cr, Ni, and Si, the hard phase contains Fe, Cr, and C, and porosity is 2.0% or less.
