Tungsten steel sintering process The classification of tungsten steel is carried out according to ISO standards. This classification is based on the material type of the workpiece. The binder phase composition mainly utilizes its strength and corrosion resistance.

The base 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, and cobalt and nickel are commonly used. Therefore, there are tungsten-cobalt alloys, tungsten-nickel alloys, and tungsten-titanium-cobalt alloys.

Tungsten-containing steels, such as high-speed steel and some hot work die steels, contain tungsten in steel, which has a significant improvement in hardness and heat resistance, but the toughness will drop dramatically.
