The difference between cemented carbide and tungsten steel
Tungsten steel is a hard alloy, but hard alloys are not necessarily tungsten steel. The difference between them is:
Carbide tungsten steel knife county is made of hard alloy and fused metal from refractory gold. It is made of powder metallurgy. It is an extremely hard alloy material. Hard alloy has high hardness, wear resistance, strength and A series of excellent properties such as good toughness, heat and corrosion resistance, especially its high hardness and wear resistance, it remains basically unchanged even at a temperature of 500 ° C, and still has a high hardness at 1000 * C. . A ceramic with certain properties of metal.
Tungsten steel is also called tungsten-titanium alloy or high-speed steel or tool steel. Hardness is 10K Vickers, second only to diamonds, refers to sintered composites containing at least one metal carbide. Tungsten steel and hard alloy have high hardness, wear resistance, strength and toughness, heat resistance and resistance. A series of excellent properties such as corrosion. The main advantage of tungsten steel is its high hardness and high wear resistance. Even though he still has a high hardness at 1000C. Easy can be called as the second diamond. The carbide component (or phase) typically has a particle size between 0.2 and 10 microns.
In the finished tungsten steel, tungsten 18% alloy steel is contained, and tungsten steel is attributed to cemented carbide, which is also called tungsten-titanium alloy. The hardness is 10K Vickers, second only to diamonds. For this reason, tungsten steel products (commonly known as tungsten steel watches) have characteristics that are not easily worn. Carbide. It is often used on lathe cutter impact drill bits, glass cutter heads, and tile cutters. It is not afraid of annealing, but it is brittle.
While cemented carbide belongs to the field of powder metallurgy, cemented carbide is also known as cermet. It is made of metal carbide (WC. TaC. NBC, etc.), or metal oxide (such as A1203, ZR02, etc.) as the primary component. Metal powder (CO. cr. mo. ni. fe, etc.) is produced by a powder metallurgy process and has certain properties of the metal.
The difference between tungsten steel and hard alloy is: also known as high-speed steel and tool steel. Tungsten steel is smelted by adding steel with tungsten and iron as steel in steelmaking technology. Its tungsten content is usually 15-25%; Cemented carbide is sintered by powder metallurgy with tungsten carbide as the main body and drilled with other bonding metals. The tungsten content is usually above 80%.
Therefore, in brief, the hardness of the HRC65, as long as the alloy can be called carbide tungsten steel knife county. Carbide, widely used in military, aerospace machining, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields, with the development of downstream industries, the demand for hard alloys continues to increase. And the future of high-tech weaponry equipment manufacturing, advances in cutting-edge science and technology, and the rapid development of nuclear energy will greatly increase the demand for high-tech content and high-quality stability of cemented carbide products.
