What is the difference between hard alloy and tungsten steel?
Most people only know that there is a hard alloy or tungsten steel, and for a long time, many people have not known the relationship between the two, let alone those who are not related to the metal industry. Kena agent Zhongshan Boshun Mold will talk about the difference between tungsten steel and hard alloy.
Cemented carbide is made of hard compounds and bonding metals of Refractory metals through powder metallurgy process. It is a kind of alloy material with extremely high hardness. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, which basically remain unchanged even at 500 ℃, and still has very high hardness at 1000 ℃. This is the reason why the price of hard alloys is higher than that of other ordinary alloys.
Application - Cemented carbide is widely used as tool materials, such as turning tool, milling tool, planer, drill, boring tool, etc., to cut cast iron, non-ferrous metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, and also to cut refractory steel, stainless steel, high manganese steel, Tool steel and other difficult to machine materials.
Tungsten steel is also called tungsten titanium alloy or high-speed steel or Tool steel. The hardness is Vickers 10K, second only to diamonds, and refers to a sintered composite material composed of at least one metal carbide. Tungsten steel and hard alloy have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. The advantages of tungsten steel mainly lie in its high hardness and wear resistance. Even at 1000 ℃, it still has a high hardness. Yi can be called the second diamond.
The difference between tungsten steel and hard alloy is that tungsten steel is smelted by adding ferrotungsten into molten steel as the raw material of tungsten, which is also called high-speed steel or Tool steel. Its tungsten content is generally 15-25%,; Hard alloy is sintered with tungsten carbide as the main body and cobalt or other bonding metals using powder metallurgy technology, with a tungsten content generally above 80%. Simply put, anything with a hardness exceeding HRC65 can be called hard alloy as long as it is an alloy.
Simply put, tungsten steel belongs to the category of hard alloys, but hard alloys may not necessarily be tungsten steel.
