What is the difference between cemented carbide and tungsten steel?

what is the difference between cemented carbide and tungsten steel？
> tungsten steel: The finished product contains about 18% tungsten alloy steel, which is classified as cemented carbide, also known as tungsten-titanium alloy. The hardness is Vickers 10K, second only to diamond. Because of this, tungsten steel products (more common tungsten steel watches) have the characteristics of not easy to be worn. Commonly used in lathe cutters, impact drill bits, glass cutter bits, tile cutters, strong and not afraid of annealing, but brittle.
Cemented carbide: cemented carbide also known as cermet in the field of powder metallurgy, is a ceramic with metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxides (such as Al2O3, ZrO2, etc.) as the primary component, participating in an appropriate amount of metal powder (Co, Cr, Mo, Ni, Fe, etc.) made by powder metallurgy method, with some characteristics of metal ceramics. Cobalt (Co) is used to bond in the alloy, that is, in the process of sintering, it can surround and tightly bond the tungsten carbide (WC) powder together, and after cooling, it becomes a cemented carbide. (The effect is equivalent to cement in concrete). Content usually: 3%--30% Tungsten carbide (WC) is the primary component that determines the properties of some metals of cemented carbide or cermet, accounting for 70% ---97% of the total composition (component ratio) Widely used in wear-resistant, high temperature resistance, corrosion resistance, harsh working environment parts or tools, tool bits.
Tungsten steel belongs to cemented carbide, but cemented carbide is tungsten steel, now customers in Taiwan and Southeast Asian countries like to use the word tungsten steel, if you talk carefully with them, you will find that most of them still refer to cemented carbide.
The difference between tungsten steel and cemented carbide is: also known as high-speed steel or tool steel, tungsten steel is made of steelmaking technology in molten steel to participate in the material smelting of tungsten iron tungsten, also known as high-speed steel or tool steel, its tungmatic content is usually 15-25%; The cemented carbide is made by sintering with cobalt or other bonded metals with tungsten carbide as the main body by powder metallurgy technology, and its tungsten content is usually more than 80%. Simply put, everything with a hardness beyond HRC65 can be called cemented carbide as long as it is an alloy, tungsten steel is only a kind of cemented carbide, the hardness is between HRC85 and 92, often used to make knives.
