What are the material requirements for tungsten steel electrical discharge machining?


During the production of tungsten steel electrical discharge machining, there are certain requirements for the material. The following HXTech Precision Company will give you a brief introduction.
What are the material requirements for tungsten steel electrical discharge machining?
The classification of tungsten steel is based on ISO standard. 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 base of tungsten steel consists of two parts: one is the hardened phase; the other is the bonding metal. The bonding metal is generally an iron group metal, commonly used as cobalt and nickel. Thus there are tungsten-cobalt alloys, tungsten-nickel alloys and tungsten-titanium-cobalt alloys.
Steel containing tungsten, such as high-speed steel and certain hot work tool steel, steel containing tungsten has a very significant increase in steel hardness and heat resistance performance, but the toughness will drop sharply.
The main application of tungsten resources is also cemented carbide, or tungsten steel. Tungsten carbide, known as the teeth of modern industry, is used to a very wide extent in tungsten steel products.
Tungsten steel has a series of excellent properties such as high hardness, wear resistance, better strength and toughness, heat resistance, corrosion resistance, etc. Especially its high hardness and wear resistance remain largely unchanged even at a temperature of 500°C and still have a high hardness at 1000°C.
Tungsten steel, also known as cemented carbide, is a sintered composite material that contains at least one metal carbide composition. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component (or phase) is typically in the range of 0.2-10 microns, and the carbide grains are bonded together using a metal binder. The binder is usually the metal cobalt (Co), but for some special applications, nickel (Ni), iron (Fe), or other metals and alloys may also be used. For a pending combination of carbide and bonding phase composition is called "grade".
