Cr-V steel is an alloy tool steel with Cr-V alloy elements. After heat treatment, its hardness is 60 HRC (Rockwell hardness).
(1) In carbon steel, chromium can significantly improve strength, hardness, and wear resistance but at the same time reduce plasticity and toughness. Chromium can improve the oxidation and corrosion resistances of steel. Thus, chromium is an important alloy element for stainless steel and heat-resistant steel.
(2) Vanadium can be added to alloy steel as deoxidizer. The addition of 0.5% vanadium to steel can refine its structure and grain and improve its strength and toughness. The carbides formed by vanadium and carbon can improve the resistance to hydrogen corrosion under high temperature and pressure.
(3) Therefore, Cr-V steel has better mechanical properties and more stable chemical properties than ordinary carbon steel.
