Properties and Applications of Superhard High Speed Steel

Performance and Application of Cemented Carbide High-speed Steel

Cemented Carbide is a metallurgical composite material made of a hard and brittle tungsten carbide powder and a cobalt binder. It has the characteristics of high hardness, high wear resistance and good red hardness. Cemented carbide is divided into cast carbide, sintered carbide, and solid carbide. The properties of cemented carbide are closely related to its composition and structure. The microstructure of cemented carbide and its composition not only determine the performance of the material, but also determine the manufacturing process and cost of the product.

Cemented carbide high-speed steel(HSS) is a kind of cold working die steel in which tungsten alloy is added and cobalt is used as a binder, and hardness (HRC) is higher than that of common tool steel. Its main applications are to manufacture cutting tools, punches, tools and dies, such as drills, reamers, taps, broaches, milling cutters, etc. The comprehensive performance of cemented carbide high-speed steel is significantly better than that of general tool steel, and its cutting performance is outstanding. Manufacturing tools need to be impacted and processed under severe conditions. Cemented carbide high-speed steel can meet the requirements of machining high-hardness materials, such as non-ferrous metals, cast iron, hardened steel and alloys.

Cemented carbide high-speed steels can be divided into different grades based on compositions such as high-quality type and powder-type. Line removal, surface roughness and surface area can be achieved by polishing and grinding tools made of cemented carbide high-speed steel. The wear resistance of the cemented carbide high-speed steel tool is much higher than that of the ordinary tool. The service life of the tool made of cemented carbide high-speed steel is usually 10 times longer than that of the ordinary tool. The hard and brittle nature of cemented carbide high-speed steel can be improved by addition of alloy elements such as cobalt and aluminum.

Cemented carbides have good oxidation resistance at high temperatures, so they are widely used in various thermal process environments. Cemented carbide high-speed steels can be processed to various shapes, and can also be used for grinding and polishing purposes, as well as for wear-resistant parts with complex shapes. Cemented carbide high-speed steel can also be used in the manufacture of oil-ring roller, valve seat and bearing contact surface, so as to reduce the wear and extends its service life.

Cemented carbide high-speed steel plays an important role in the modern industry. Its outstanding performance has been applied in many fields and has made remarkable achievements. Its main features are high hardness and wear resistance and good red hardness, which make it the material of choice for cutting tools in modern industry. In the future, cemented carbide high-speed steel will continue to be used in more fields and become the best choice for many tools and components.

Introduction

With the rapid development of modern industrial technology, precision cutting tools have become an indispensable tool in many production processes.High speed steel is also known as steel, which is a kind of superhard alloy .It is not only hard but also tough, is a kind of high performance steel, suitable for cutting complex shape of the workpieces.

Main Performance

High speed steel has the advantages of high hardness, high temperature wear resistance and high cutting performance, and its heat resistance and red hardness are far higher than that of ordinary steel.It is suitable for the manufacture of cutting tools that require high cutting speed and wear resistance under high temperature or difficult working conditions.It is made of tungsten, molybdenum, chromium and other elements to form an alloy steel after hot-blowing and heat-treating.

Applications

High speed steel is widely used in cutting tool production, and is suitable for cutting hard and brittle materials, such as carbon-containing materials, non-ferrous metals, etc. It is suitable for the manufacture of drill bits, taps, reamers, milling cutters, saw blades, and also used in precision injection molding, punching, and other production processes.

Conclusion

High speed steel has high hardenability, high degree of wear and tear, and strong cutting ability, which is incomparable to other metals.It has good performance and strong processing capacity, and plays an important role in various industrial production processes.
