粉末高速钢#高碳合金M4钢带/刀具钢带
High speed steel belongs to high carbon high alloy ledeburite steel, special steel is with special heat treatment in the powder metallurgy high speed steel can obtain high hardness (HRC63 ~ 70), and, and, in 550 ~ 600 ℃ can still maintain a high hardness (HRC 60 or above), and high wear resistance of heat-resistant wear-resistant steel class, its main use for the fabrication of various machine tool cutting tools, mold is partly used in high load, high temperature air bearings and special alloy wear parts, etc.
Metallurgical powder high speed steel, powder metallurgy high speed steel, for short or PM high speed steel. By powder metallurgy method (atomized powder under the hot isostatic pressing treatment) was dense steel billet, then through forging, rolling, etc. The thermal deformation of high speed steel profiles, hereinafter referred to as powder high speed steel. Uniform powder high speed steel group, tiny grain, eliminates the fused cast high speed steel is difficult to avoid segregation, so than fused cast high speed steel of the same component has higher toughness and abrasion resistance, but also has the properties and the heat treatment deformation of small, forged grinding performance is good wait for an advantage.
高速钢属于高碳高合金莱氏体钢，是特殊钢中通过特殊热处理 粉末冶金高速钢可以获得极高硬度(HRC63~70),，而且在550~600℃仍可保持高硬度(HRC 60以上)和高耐磨性的耐热耐磨钢类，其主要用途为制造各种机床的切削工具, 也部分用于高载荷模具, 航空高温轴承及特殊耐热耐磨零部件等。
　　冶金粉末高速钢，简称粉冶高速钢,或PM高速钢。采用粉末冶金方法（雾化粉末在热态下进行等静压处理）制得致密的钢坯，再经锻、轧等热变形而得到的高速钢型材,简称粉末高速钢。粉末高速钢组织均匀,晶粒细小,消除了熔铸高速钢难以避免的偏析,因而比相同成分的熔铸高速钢具有更高的韧性和耐磨性，同时还具有热处理变形小、锻轧性能和磨削性能良好等优点。
