The main component of tungsten steel is tungsten carbide What is the composition of tungsten steel

Tungsten. Also known as cemented carbide, the main components of cemented carbide are tungsten carbide and cobalt, which account for 99% of all components, and 1% is other metals, so it is also called tungsten steel. It is often used in high-precision machining, high-precision tool materials, lathes, percussion drill bits, glass knife heads, and tile cutters.

It is a rare metal.

of the list. Tungsten steel (cemented carbide) has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500, it remains basically unchanged, and it still has a high hardness at 1000. Tungsten steel is classified according to ISO standards.

Carry out. This classification is based on the material type of the workpiece (e.g. P, M, K, N, S, H grades). The binder component is mainly used for its strength and corrosion resistance.

Tungsten steel, also known as tungsten carbide, refers to a sintered composite material containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steel. The grain size of the carbide components (or phases) is usually between microns, and the carbide grains are held together using a metal binder.

Binders are usually referred to as the metal cobalt (CO), but can also be used for some specific applications, such as nickel (Ni), iron (Fe), or other metals and alloys. For a composition combination of a carbide and a binder phase to be determined, it is called a "grade".

Plasma-enhanced chemical vapor deposition (PECVD): A gas mixture of tungsten and methane (or other carbon-containing compounds) is introduced into the reaction chamber to produce an unsaturated tungsten carbide film by the plasma excitation reaction gas. High Temperature Reaction Method:

Tungsten and carbon powder are mixed and reacted at high virtual purity temperature to generate unsaturated tungsten carbide powder. Among them, the preparation of unsaturated tungsten carbide films by PECVD method has the advantages of simple process, low cost and fast preparation speed, and is suitable for large-scale production and industrial preparation. The high-temperature anti-ant reaction method is suitable for the preparation of unsaturated tungsten carbide powder, which is suitable for the preparation of products with different forms and particle sizes, such as blocks, particles, nano-scale powders, etc.

Unsaturated tungsten carbide is a binary alloy composed mainly of tungsten and carbon. Unsaturated tungsten carbide is formed by a special heat treatment process of tungsten. The specific heat treatment process consists of the following steps:

Pure tungsten is heated to a high temperature to form tungsten W2C on its surface. The tungsten parts formed by tungsten are placed in a high-temperature furnace and heat treated under certain pressures and over a specific period of time. At high temperature and pressure, tungsten W2C will decompose and re-carbonize to form unsaturated tungsten carbide WC1-X, where X is a value between 0.

This special heat treatment method can make the tungsten atoms and carbon atoms form a uniform distribution of solid solutions, so as to form unsaturated tungsten carbide. This alloy is generally characterized by high hardness, wear resistance, permeability, and corrosion resistance, making it widely used in the manufacturing industry, mining industry, and aerospace industry.

Tungsten steel: about 18% tungsten alloy steel in the product.

Tungsten steel belongs to cemented carbide.

It is also called tungsten titanium alloy.

It has a hardness of 10k on the Vickers scale, second only to diamond. Because of this, tungsten carbide products (commonly tungsten carbide watches) have the characteristics of not being easily worn. It is often used in lathe cutters, percussion drill bits, glass knife bits, and tile cutters, which are hard and not afraid of annealing, but brittle.

Tungsten carbide: belongs to powder metallurgy.

Category. Tungsten carbide, also known as cermet, is made of metal carbides (WC, TAC, TIC, NBC, etc.) or metal oxides.

Such as Al2O3, Zro2, etc.) as the main component, adding an appropriate amount of metal powder (CO, CR, MO, NI, Fe, etc.) through powder metallurgy method to make ceramics with certain characteristics of metal.

Cobalt (CO) is used to bind alloys, that is, in the sintering process, it can hold tungsten carbide.

WC) powders are surrounded and tightly bonded together, and when cooled, they become cemented carbide. (The effect is equivalent to cement in concrete). The content is usually: 3%--30%.

Tungsten carbide (WC) is the main component that determines the properties of some metals of this tungsten carbide or cermet, accounting for 70%-97% (weight ratio).

It is widely used in wear-resistant, high-temperature-resistant, corrosion-resistant, harsh working environment parts or cutters, tool heads.

Tungsten steel belongs to cemented carbide, but tungsten carbide is not necessarily tungsten steel, which is now in Taiwan and Southeast Asia.

Customers in the country like to use the word tungsten steel, if you talk to them carefully, we will find that most of them still refer to our cemented carbide...

1. It is widely used as high-speed cutting turning tools, kiln structural materials, jet engine parts, cermet materials, resistance heating elements, etc.

2. It is used to manufacture cutting tools, wear-resistant parts, smelting crucibles for copper, cobalt, bismuth and other metals, and wear-resistant semiconductor films.

3. It is used as a super loss hard tool material and wear-resistant material. It can form a solid solution with many carbides. WC-TIC-CO carbide tools are already widely used.

It can also be used as an aerospace material as a modified addition to NBC-C and TAC-C ternary carbides, which can reduce the sintering temperature while maintaining excellent performance.

4. Tungsten carbide (WC) powder is synthesized by tungsten anhydride and graphite at a high temperature of 1400 1600 in a reducing atmosphere. Dense ceramic products can be prepared by hot pressing sintering or hot isostatic sintering.

1. Tungsten steel refers to the alloy material obtained by mixing, pressing and sintering by a series of processing technologies using WC and CO powder as the main raw materials by powder metallurgy methods. It has the characteristics of hardness, high strength, corrosion resistance, and stainless steel.

2. It is widely used in hardware, machinery, chemical industry, national defense and other industries to produce high-precision and wear-resistant key components.

3. Tungsten steel has high density, g cm2: different, the density of tungsten steel materials for different uses is not consistent, it can also be said that tungsten steel materials of different densities are used differently, please pay attention when purchasing.
