Tungsten steel, also known as cemented carbide, is a sintered composite material containing at least one metal carbide composition. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steels. The grain size of the carbide component (or phase) is typically between 0.2 and 10 microns and the carbide grains are bonded together using a metal binder. The binder is usually the metal cobalt (Co), but for special applications nickel (Ni), iron (Fe), or other metals and alloys may also be used. The composition of a pending combination of carbide and bonding phase is called a "grade".
The classification of tungsten steels is based on ISO standards. This classification is based on the material type of the workpiece (e.g. P, M, K, N, S, H grades). The bonded phase composition is mainly used for its strength and corrosion resistance.
The matrix of tungsten steel consists of two parts: one part is the hardened phase; the other part is the bonding metal. The bonding metal is generally an iron group metal, commonly cobalt and nickel. This gives rise to tungsten-cobalt alloys, tungsten-nickel alloys and tungsten-titanium-cobalt alloys.
In steels containing tungsten, such as high-speed steels and certain hot work tool steels, the presence of tungsten in the steel has a very significant increase in hardness and heat resistance, but the toughness decreases dramatically.
The main application of tungsten resources is also in cemented carbide, also known as tungsten steel. Tungsten carbide, known as the teeth of modern industry, is used to a very wide extent in tungsten steel products.
Tungsten steel performance characteristics.
1. High density, g/cm2: 11.0 ~ 15.0 vary, the density of tungsten steel materials for different purposes is not the same, it can also be said that different density of tungsten steel materials for different purposes, please note when buying.
2. High strength, the strength of tungsten steel materials for different purposes is not consistent, it can also be said that the different strength of tungsten steel materials for different purposes, in the purchase is to pay special attention to this.
3. High hardness, 82.0 ~ 93.6 HRA, equivalent to 69 ~ 81 HRC, the hardness of tungsten steel materials for different purposes is not consistent, it can also be said that the different hardness of tungsten steel materials for different purposes, in the purchase is to pay special attention to this.
4. Red hardness is good, up to 900 ~ 1000℃, keep 60HRC when not deformed.
5. Good wear resistance, can be processed stainless steel, cast iron and other hard metal materials.
