1. The surface condition of tungsten steel has a great influence on its bending strength. In the process of manufacturing tungsten steel tools, various cracks on the surface should be prevented, otherwise the bending strength of tungsten steel will be greatly affected.
2. The brittleness of tungsten steel is very high and is independent of temperature. At room temperature, the impact toughness of quenched steel is 1-2 times greater than that of tungsten steel. Therefore, impact compression of tungsten steel is not allowed when welding tungsten steel. Don't make them collide or be impacted during transportation.
3. It is important to understand the linear expansion coefficient of tungsten steel, which is more than twice lower than that of high-speed steel. In the inlay welding of tungsten steel and high-speed steel, due to the difference in linear expansion coefficient between tungsten steel and high-speed steel, when the inlay-welded mold is cooled, the stresses on the inner and outer layers are different, forming inward tensile stress on the surface. After inlay welding, measures should be taken to eliminate stress, otherwise the tungsten steel will crack or desolder.
