The application of tungsten steel tool materials can be said to be more extensive, but some users will experience material wear when using the tungsten steel tool materials. What is the reason? Let's take a look.
Phase change wear of tungsten steel tool materials: when various steel tungsten steel tools at a certain cutting temperature, the metallographic structure of the surface layer of the tungsten steel tool material will transform from tempered martensite to bainite, troostite or primeite, and the hardness is greatly reduced, which accelerates the wear of tungsten steel tools. People in the mold accessories industry will know something about tungsten steel tools. Tungsten steel tools are used as cutting tools, and the correct use is also to improve the tools.
Bonding wear of tungsten steel tool materials: when the cutting temperature is slightly higher, some protruding points on the front and flank surfaces of the tungsten steel tool will bond with the workpiece and chips during relative movement, and will be gradually cut and torn away by the workpiece or chips.
The greater the chemical affinity between the tungsten steel tool material and the workpiece material, the more brittle the nature of the tungsten carbide cutter material, the more uneven the material, and the more serious the bond wear. Generally, tungsten steel tool materials are prone to this kind of wear within the cutting speed range that produces built-up edge.
The above is the reason for the wear of the tungsten steel tool materials we have organized for you. Betalent will continue to organize more related content for you.
