High speed steel of industrial blades
- Jul 03, 2018 -

High speed steel (HSS) is a tool steel with high hardness, high abrasion resistance and high heat resistance. High speed steel has good technical performance and good strength and toughness, so it is mainly used to manufacture complex thin blade and impact resistant metal cutting tools, as well as high temperature bearing and cold extrusion dies. In the manufacturing of our industrial blades, high-speed steel is mostly used, such as Guillotine knife for paper cutter, circular upper blade, planer knife...Two popular HSS material is W18Cr4V, W6Mo5Cr4V2, and W18Cr4V is the most people’s choice for guillotine knife for paper cutter.


Material composition of W18Cr4V:

C: 0.7-0.8;  Cr: 3.8-4.4;  W: 17.5-19.0;  V: 1.0-1.4;  Mo≤0.30;  Mn<0.4;  Si<0.4;  S≤0.03;  P≤0.03


Hardness of W18Cr4V: 66-68HRC
