For powder metallurgy alloy steel powder, and a manufacturing method of powder metallurgy for the alloy steel powder

摘要

PROBLEM TO BE SOLVED: To provide an alloy steel powder for powder metallurgy that contains Cu and enables a sintered part having tensile strength of 600 or more MPa to be manufactured at low cost.;SOLUTION: An alloy steel powder for powder metallurgy is a water-atomization alloy steel powder formed of prealloyed alloy elements, wherein the steel powder contains, by mass, 0.3 to 0.5% Cr, 0.1 to 0.3% Mn, 0.1 to 0.5% Mo, 1 to 4% Cu, and the balance Fe with inevitable impurities.;COPYRIGHT: (C)2013,JPO&INPIT
