Cemented carbide drawing die small make up to tell you the introduction of tungsten steel
Tungsten steel (carbide) has high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even under the temperature of 500 ℃ is basic remains the same, there are still very high hardness at 1000 ℃.
Carbide, tungsten steel, also known as refers to contain at least one metal carbide sintering of composite materials. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, tantalum carbide, a common component of tungsten steel. Carbide components (or phase) of the grain size is usually between 0.2 and 10 micrometers, carbide grain use metal binder together. Binder usually refers to the metal cobalt (Co), but for some special purpose, nickel (Ni), iron (Fe), or other metal and alloy can also be used. For a backlog of carbides and the composition of the binding phase is called "brand".
The classification of the tungsten steel according to ISO standards. This classification is based on the workpiece material kind (such as P, M, K, N, S, H type). Binding phase composition mainly is to use its strength and corrosion resistance.
Tungsten steel substrate consists of two parts: part of hardening phase; The other part is a metal bonding. Bonding metal is iron group metals commonly, commonly used is cobalt and nickel. So there will be a tungsten cobalt alloy, tungsten cobalt tungsten nickel alloy and titanium alloy.
The main application of tungsten resources is cemented carbide, tungsten carbide. Cemented carbide, known as the teeth of modern industry, tungsten steel products has a very wide range of use level.
