Experimental Investigation on Wear Resistance of Low-alloyed Cast Steel
The effects of ductile iron(QT) and steel 40 heat treatment states on the wear resistance of cast steel were studied by shaft-ring friction method.The results show that the effects of steel 40 shaft specimen under different heat treatment on the wear resistance of the cast steel ring is that when the shaft hardness and the speed decrease,the wear resistance decreases.AsforQTspecimen,whentheshafthardnessandthespeedincrease,thewearresistanceofthecast steel ring reduces.
