ALLOY STEEL POWDER FOR POWDER METALLURGY.

摘要

This new alloy steel powder consists of W (0.2-2.0 wt.%, pref. 0.2-1.6 wt.%), Ni (0.8-3.0 wt.%, pref. 1.0-2.5 wt.%) and Fe and unavoidable impurities (the residual) Mo or Cu can be added as fourth and fifth components in the amts. Mo 0.1-1.0 wt.%, (pref. 0.2-0.8 wt.%), Cu 0.2-2.0 wt.% (pref. 0.2-1.0 wt.%). However the total amt. of Ni and Cu should lie between 1.0 and 2.5 wt.%. Both Mo and Cu can be added together as the fourth and fifth components in the amts. Mo 0.1-1.0 wt.% (pref. 0.2-0.8 wt.%), Cu 0.2-2.0 wt.% (pref. 0.2-1.0 wt.%). In this case also the total amt. of Ni and Cu should be between 1.0 and 2.5 wt.%.
