概要

The effect of V addition up to 5% on properties of high C-5Cr-W-Mo, high C-8Cr-W-Mo and high-C-12Cr-Mo steel was investigated in comparison with high C-high Cr steel (CRD). By the addition of V, each transformation temperature was raised and appropriate quenching temperature range was heightened. At the same time, the amount of the retained austenite was decreased and fine structure was gained. Such properties as dimensional change, toughness and wear resistance of these specimens were improved as the V content were raised as well as the Cr at the same V content series. The specimens containing a high V content in 5% Cr and 8% Cr base steels showed better wear resistance, while the toughness was generally inferior to those of CRD steel. However the specimens of a higher V content in 12% Cr-base steels were superior in toughness and wear resistance to CRD steel.
