HARD POWDER HIGH IN PRODUCTIVITY AND CORROSION RESISTANCE WITH INEXPENSIVE PRICE AND PROJECTION MATERIAL FOR SHOT-PEENING AND IRON-BASED ABRASION RESISTANT SINTERED ALLOY HAVING HARD PARTICLE DISPERSED

摘要

PROBLEM TO BE SOLVED: To provide a hard powder high in productivity and corrosion resistance with inexpensive price and a projection material for shot-peening and an iron-based abrasion resistant sintered alloy with the hard particle dispersed.SOLUTION: There is provided a hard powder having, by mass%, C:0.6 to 2.4%, Cr:36 to 60%, Mn:0.1 to 10% and the balance Fe with inevitable impurities. Also there are provided a hard powder containing one or more kind of, by mass%, Mo:less than 10%, Si:less than 2%, Ni:less than 15% and a projection material for shot-peeing and an iron-based abrasion resistant sintered alloy with the hard particle dispersed.SELECTED DRAWING: None
