There are differences in raw materials, composition, properties and applications between cemented carbide and tungsten steel.
- Raw materials and ingredients: Cemented carbide is a high-hardness alloy material made from hard compounds of refractory metals and bonded metals through a powder metallurgy process. It usually contains metal powders such as tungsten, cobalt, and titanium. It has high hardness and high resistance. Wear, high strength, high corrosion resistance and other advantages. Tungsten steel, also known as tungsten-titanium alloy or high-speed steel or tool steel, is made by adding ferrotungsten to molten steel through steelmaking. Its tungsten content is generally 15-25%.
- Performance: Carbide has high hardness and wear resistance. Its hardness can reach HRA87~93 at normal temperature. Its wear resistance is more than 10 times that of steel. It still maintains high hardness and wear resistance at high temperatures of 500°C. The strength is 3 to 5 times that of high-speed steel. Tungsten steel also has high hardness and wear resistance. It still maintains good hardness and strength at high temperatures and has a certain degree of toughness.
- Application: Carbide is widely used in mechanical processing, mining, petroleum, chemical industry and other fields, such as cutting tools, drill bits, saw blades, abrasives, nozzles, etc. It is an important industrial consumable. Tungsten steel is mainly used to make high-speed cutting tools, cutters, drill bits, milling cutters, etc., and is widely used in the fields of machinery manufacturing and tool manufacturing.
To sum up, although cemented carbide and tungsten steel both have the characteristics of high hardness and wear resistance, they have differences in raw materials, composition, performance and applications. Therefore, it is necessary to select suitable materials according to specific usage scenarios.
