1. The surface state of tungsten steel has a great influence on its flexural strength. In the process of manufacturing tungsten steel tools, various cracks should be prevented on its surface, otherwise it will have a great impact on the flexural strength of tungsten steel.
2. The brittleness of tungsten steel is very high, and it is independent of temperature, and the impact toughness of quenched steel is 1-2 times greater than that of tungsten steel at room temperature. Therefore, impact compression of tungsten steel is not allowed when inlay and welded tungsten steel. Do not collide or be impacted during transportation.

3. It is important to understand the linear expansion coefficient of tungsten steel, which is more than twice as low as that of high-speed steel. In the case of tungsten steel and high-speed steel inlay welding, due to the difference in the linear expansion coefficient between tungsten steel and high-speed steel, when the mold is cooled, the stress on the inner and outer layers is different, and the inward tensile stress is formed on the surface. After inlay welding, measures should be taken to relieve stress, otherwise tungsten steel will crack or desolder.
