Tungsten steel, also known as high-speed steel, is an alloy composed of carbon, tungsten, chromium, and other metallic elements. It is widely used in the processing of industrial machinery parts due to its high hardness (HRC 60-65), excellent wear resistance, high-temperature resistance, and corrosion resistance.
There are several types of tungsten steel materials.
- High-Speed Steel High-speed steel, also known as hard alloy or tool steel, is a special alloy steel with a carbon content ranging from 0.3% to 1.5%. It is produced using powder metallurgy methods. High-speed steel possesses high hardness (HRB greater than or equal to 55), excellent wear resistance, and impact resistance, as well as good toughness. It is used for manufacturing various cutting tools, mold cutting tools, rolling knives, and drill bits for automatic lathes. It is also used to produce cold stamping die plates such as woodworking saw blades and planer edges, as well as pressure plates for hot working dies like wire drawing dies.
- Hard Alloy Hard alloy, also known as cemented carbide, is a multi-phase structure superhard material formed by bonding a plasticized state of refractory metals, such as cobalt-aluminum-silicate-based matrix, with a binding metal. It typically contains a large amount of hardening phases such as tungsten carbide, titanium carbide, cobalt oxide, or copper oxide. In addition to carbon, it also contains a certain amount of cobalt, nickel, chromium, molybdenum, vanadium, nitrogen, boron, titanium, and various other metallic and non-metallic impurities. The microstructure consists of a ferrite matrix with dendritic graphite composite organization, forming a fibrous network structure or amorphous grain composition. The density is approximately 5.25 g/cm³.
- Sintered Cobalt-Based Heat-Resistant Aluminum Alloy Sintered cobalt-based heat-resistant aluminum alloy is a new type of high-temperature resistant material made by adding an appropriate amount of antioxidants to pure aluminum. This product exhibits excellent high-temperature resistance, with a melting point exceeding 1670°C, while maintaining good thermal conductivity and corrosion resistance. It possesses high strength and is resistant to deformation. Additionally, it offers advantages such as excellent weldability and processability.
- Stainless Steel Stainless steel refers to steel plates that are resistant to weak corrosive media such as air, steam, water, and acid organic chemical corrosive media (including acid-base salts).
