The application of tungsten steel materials is now very extensive, but many users say that some tools made of tungsten steel materials will undergo diffusion wear after application. What is the reason? Let's find out together.
When using tungsten steel tools for high-speed cutting, the cutting temperature can reach 800°C. At this time, the Co, C, W, Ti and other elements in the tungsten steel will diffuse and penetrate into the chips and the workpiece.
On the other hand, the iron element in the workpiece material will also diffuse to the surface of the tool, causing the metallographic structure of the tungsten steel tool material to change, and the strength and hardness of the tungsten steel tool material are reduced, which promotes the rapid wear of the tungsten steel tool.
The higher the cutting temperature, the faster the diffusion speed, and the faster the tungsten steel tool wear; the diffusion speed of Ti is slower than that of C, Co, W and other elements.
Therefore, YT tungsten steel has better wear resistance than YG tungsten steel; the surface of coated tungsten steel deposits more difficult to diffuse materials, which is better than general tungsten steel.
