Sichuan Liaofu Special Steel Industry Co., Ltd,A comprehensive professional manufacturing enterprise which has integrating smelting, electroslag remelting, forging, rolling, heat treatment and machining.The company has a complete set of advanced production equipment and production prehard precision plate,and so on.High speed steel tool bit with materialhigh speed steel: 6542, 1841, 9341, 4341, 4241, 5241, M35.M2 M42
High speed steel turning tools generally go through high temperature forging, salt bath furnace quenching, hardening, and then tempering to increase toughness to achieve the most reasonable performance, flat grinding machine polishing surface, inspection and selection, typing, packaging and other processes, so that qualified high speed steel turning tools can normally leave the factory, general high speed steel materials according to its element content is divided into W6Mo5Cr4V2 and other materials, The hardness ranges from 62-65 degrees Rockwell. In addition, in order to adapt to higher hardness, there are also high speed steel products containing cobalt. By increasing the content of cobalt to improve the hardness, such as M42, co3n, M2AL, M35 and other materials, the quasi-hardness can reach about 65-70 degrees Rockwell. In recent years, the V3N superhard high speed steel developed by our own, even the hardness reaches 68-70, which makes the domestic high speed steel very competitive in the world. High speed steel turning tool is a widely used product in the early industrial underdeveloped period. Its advantage is that it has a high utilization rate through continuous use and grinding. Its disadvantage is that it cannot break the hardness bottleneck due to its own material reasons.High speed steel turning tools generally go through high temperature forging, salt bath furnace quenching, hardening, and then tempering to increase toughness to achieve the most reasonable performance, flat grinding machine polishing surface, inspection and selection, typing, packaging and other processes, so that qualified high speed steel turning tools can normally leave the factory, general high speed steel materials according to its element content is divided into W6Mo5Cr4V2 and other materials, The hardness ranges from 62-65 degrees Rockwell.

High speed steel knife advantages and disadvantages
1. High speed steel generally refers to the high alloy steel containing W, Cr, V and other elements, common grades are W18Cr4V, W6Mo5Cr4V2 and so on.
2. The heat treatment process of high speed steel is relatively complex, which is usually tempered twice after quenching and tempering. Especially, the tempering process is not easy to control, which is prone to crack and cold and brittle.
3. Because of its high hardness and hardness, high speed steel is generally used for manufacturing tools, cutting tools, such as turning tools, drills, broach tools, etc., which are used in heavy machine repair and processing industry.
4, general military products, such as sabers, the use of low cost, easy to control the process of high carbon steel manufacturing, such as 440C class high carbon steel.
5, heating the steel annealing, reduce the steel hardness, increase the toughness. Makes the high speed steel less brittle.
