Tungsten steel profile: tungsten is one of the most high temperature resistant metal. Tungsten steel also inherited the excellent characteristics of tungsten. Made of ordinary carbon steel lathe tool, heated to 250 ℃ above will become soft, nature also can't cutting metal. However, made of tungsten steel lathe tool, the temperature as high as 1000 ℃, still hard as before. In 1900, it was the first time in the world's fair exhibition made of tungsten steel cutting tool. However, due to the tungsten steel cutting tool has the very big superiority, then rapidly in industry widely. In just 50 years, as a result of the use of tungsten steel cutter, metal cutting speed increased by two hundred times, increased to more than two kilometers from ten meters per minute. Heat resistant tungsten steel is still keep a good mechanical strength and flexibility.

Tungsten steel is cemented carbide and tungsten titanium alloy. For the vickers hardness 10 k, second only to diamond. Because of this, tungsten steel products (common tungsten steel watches), can not easily be wear characteristics. Often used in lathe, drill bit, glass cutter head, cutter, ceramic tile is hard and not afraid of annealing, but very brittle. Among the rare metal

Containing tungsten steel products, such as high speed steel, and some steel, tungsten steel contains on the steel hardness and heat resistance performance has significantly improved, but the toughness will decline sharply.

Cemented carbide in the main ingredients of tungsten carbide and cobalt, it accounts for 99% of all ingredients, 1% for other metals, so also known as tungsten steel

Tungsten steel (carbide) has high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance, even under the temperature of 500 ℃ is basic remains the same, there are still very high hardness at 1000 ℃. Hard alloy is widely used as a material, such as turning, milling, planing tool, drilling, boring cutter, etc., used for cutting cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, can also be used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel and other hard processing material. Now new type of cemented carbide cutting speed is equal to the carbon steel hundreds of times.

Tungsten steel (carbide) can also be used to make the drilling tools and mining tools, drilling tools, measuring tool, wear-resistant parts, metal abrasive, cylinder liner, precision bearing, nozzle, etc.
