K30 Tungsten Steel Sheets For Making High Temperature Resistant Parts
The Tungsten Steel Sheets are mainly made of tungsten carbide, tungsten carbide and cobalt cobalt powder mixed by metallurgical methods such as crushing, ball milling, pressing, and sintering. The main alloy components are WC and Co. The content of WC and Co in tungsten carbide sheets for different purposes is different, and they are widely used. Tungsten steel is one of many materials of tungsten carbide. It is named after its rectangular thin plate (or square), also known as tungsten steel sheets.
Technological Process
Pulverization → formulation according to application requirements → wet grinding → mixing → crushing → drying → screening → adding molding agent → re drying → preparing mixture after screening → granulation → pressing → forming → sintering → forming (blank) → flaw detection → packaging → warehousing

Application range classification
- Tungsten steel sheets are suitable for machining at high temperature. It can be used to make cutting tools, structural materials of kilns, jet engines, gas turbines, nozzles, etc. The super coarse tungsten carbide powder raw material for super coarse tungsten carbide co cemented carbide has a series of advantages such as complete crystal structure, few structural defects, high microhardness, small micro strain and certain plasticity. The cemented carbide manufactured with it has good toughness, impact resistance, high high high temperature hardness, high thermal conductivity and small creep deformation. It is widely used in mining tools, oil drilling and production tools Shearer mining tools, shield machine tools for tunnel engineering, stamping dies, composite rollers, hard surface spraying and spray welding of metal surface, etc.
Performance characteristics of tungsten steel sheets
Tungsten steel sheets have the characteristics of high hardness, high hardness, good wear resistance, high elastic modulus, high compressive strength, good chemical stability (acid resistance, alkali resistance, high temperature oxidation resistance), low impact toughness, small expansion coefficient, etc., heat conduction The properties and conductivity are similar to iron and its alloys.
