The composition and microstructure of high vanadium high speed steel （HVHSS） and the influence of modification treatment on the morphology and distribution of the vanadium carbide were summarized. The properties and mechanism of HVHSS under abrasive wear, impact wear, rolling wear, sliding wear and roll sliding wear were introduced, and the effects of heat treatment, carbon and vanadium content and.alloy elements on wear properties of HVHSS were discussed. Additionally, the reason for good wear-resisting performance of HVHSS was analyzed. HVHSS is one of the most important directions, and has a broad development prospects in current researches.
