What Kind of Material Is Tungsten Steel?

The hardness of tungsten steel is second only to diamond, but it cannot be used as a blade for ordinary use.

Speaking of tungsten steel, I believe that many friends rarely hear it. But when it comes to its other name: cemented carbide, everyone should still be familiar with it because it is necessary to deal with it in mechanical manufacturing. Cemented carbide is a super-hard synthetic material, and its main component is black tungsten powder after sintered carbonization.

According to the different needs of the product, its composition is as high as 85% to 97%. The rest of the content is mainly cobalt, titanium, other metals, and binders. We often say that cemented carbide is tungsten steel. Strictly speaking, tungsten steel belongs to cemented carbide. Tungsten is a special dense metal with a very high melting point and good electrical conductivity. So it is used as an electric filament and the electrode of argon arc welding. Tungsten steel is mainly characterized by its high hardness and wear resistance.


Even at a high temperature of thousands of degrees, tungsten steel has high hardness. The hardness of tungsten steel is second only to diamond. Known as the tooth of modern industry, tungsten steel has many excellent properties, such as heat resistance, corrosion resistance, and good stability. Therefore, it is widely used in the manufacturing of high-speed cutting tools, such as tap drills, milling cutters, saw blades, and high-temperature rocket engine nozzles.

Since the Rockwell hardness of tungsten steel is as high as 90HAR, it has low toughness and is particularly brittle. Tungsten steel products are likely to be broken when dropped on the ground, so tungsten steel is not suitable for daily use of blades. The production process of tungsten steel is powder metallurgy. First, the mixed tungsten powder is pressed into a mold and then heated to a certain temperature in a sintering furnace. After cooling, the required tungsten steel blank is obtained. After cutting and grinding, the finished product comes out. With the development of new materials and technologies, many countries are developing new superalloys, and tungsten steel is the most interesting metal in modern material science and metallurgy, and tungsten steel is also becoming an increasingly important material in alloys. Therefore, it is possible to develop stronger new alloys through the special properties of tungsten steel.
