Tungsten steel, an exceptional high performance material, stands out as the material of choice for many demanding applications. It is a sintered composite material made up of a variety of metal carbides, commonly known as tungsten carbide powder, cobalt carbide powder, niobium carbide powder, titanium carbide powder and tantalum carbide powder.
The most striking characteristic of tungsten steel is its outstanding hardness and strength, which enables it to withstand extremely high levels of stress and friction, and to maintain stable performance even under extreme conditions.
The outstanding advantage of tungsten steel is that it also has excellent heat and corrosion resistance. While many materials lose their properties due to thermal expansion in high temperature environments, tungsten steel maintains its stable shape and properties at high temperatures. In corrosive environments such as humid, acidic or alkaline, tungsten steel can maintain its original lustre and performance for a long time.
The manufacturing process of tungsten steel, especially its sintering and forming stage, is the key to ensure its performance. After the powder is pressed into a billet, it will enter the sintering furnace for heating. This process can be divided into several stages, firstly, the de-former and pre-sintering stage, which is to remove impurities and residues from the material; secondly, the solid phase sintering stage, in which the powders are gradually bonded together to form a strong structure; then the liquid phase sintering stage, in which some of the powders are melted, which further strengthens the material; and finally, the cooling stage, in which the material cools down from the sintering temperature to room temperature, ensuring its structural stability. Tungsten steel can be affected by a number of factors during the sintering process that can cause it to deform. These factors include carbon gradients, cobalt gradients, temperature gradients, density gradients in the press work, improper loading of the boat and shrinkage factors. These factors must be precisely controlled in order to ensure that the shape and properties of tungsten steel meet the requirements.
Tungsten steel has a wide range of applications in several fields. For example, in the field of mould making it can be used as stretching mould, drawing mould, wire drawing mould, and many other moulds. In the field of mining industry, tungsten steel is used to make various kinds of drills and cut-off teeth and other mining products. In addition, tungsten steel is also used in the manufacture of sealing rings, wear-resistant materials, nozzles and grinding machine mandrels.
