摘　　要：介绍了河冶科技自主研发的丝锥用3V级HYTV3高性能高速钢与国外某厂3V级高速钢的性能。通过合金化设计、精准化工艺控制,HYTV3高速钢获得细小均匀的MC碳化物组织。通过改变磨削加工类型、砂轻材质、砂轮转速参数,对比了M2、HYTV3、M3、GV3、M35五种材质的耐磨性和可磨削性,证明HYTV3高速钢在保持良好耐磨性的同时具有优异的可磨削性。The performance of 3V grade high performance high speed steel HYTV3 for taps developed by He Ye Science and Technology Company and that of a foreign company is introduced in this paper. Fine and uniform MC carbide microstructure is obtained in HYTV3 high speed steel by alloying design and precise process control. The abrasion resistance and grindability of M2,HYTV3,M3,GV3 and M35 are compared by changing the grinding types,sanding lightweight material and grinding wheel speed parameters,which proves that high speed steel HYTV3 has excellent grindability and good wear resistance at the same time.
