K20 Tungsten Steel Plates For High-Temperature Parts Application

Tungsten Steel Plates are mainly made of WC tungsten carbide and co cobalt powder mixed by metallurgical methods through pulverization, ball milling, pressing and sintering. The main alloy components are WC and Co. the component contents of WC and CO in tungsten carbide plates for different purposes are different, and they are widely used. It is named after its rectangular plate (or square), also known as tungsten steel plates.

Performance Characteristics of tungsten steel plates

Tungsten steel has high hardness, especially at high temperature. WC can be well wetted by metal melts such as CO, Ni and Fe, especially cobalt melt has good wettability to WC. WC can be dissolved in these metal melts when the temperature increases above the metal melting point, and WC can be precipitated when the temperature decreases. These excellent properties make it possible to use metals such as cobalt or nickel as binder phase materials and form wear-resistant coatings with good wear resistance after high-temperature sintering or coating treatment.

Scope of application

Tungsten steel is suitable for mechanical processing at high temperatures, and can be used to make cutting tools, structural materials for kilns, jet engines, gas turbines, nozzles, etc. It is widely used in mining tools, oil drilling tools, coal mining tools, shield tools for tunnel engineering, stamping dies, composite rolls, hard surface spraying and spray welding of metal surfaces, etc.
