Basic performance requirement

No matter how to choose die steel sheet, the hardness, strength and toughness of its foundation should meet the requirements. After all, the molds we want to process are different, so the requirements for materials should be determined in advance. In particular, to ensure good wear resistance, so that even long-term use is not easy to wear, will not affect its accuracy.

Thin tool steel plate NOTE:

At the same time, we should also pay attention to its fatigue performance, because the mold will be subjected to mechanical shock and thermal shock in the process of working, so we must ensure that the fatigue performance is in line with the regulations. You can first test the performance of the steel, get the sample to determine its fatigue, and then choose the appropriate steel.

Product introduction

In high speed steel, die steel, tool steel sheet is the main product, used in the manufacture of circular saw blades, paper cutter, flat cutter, cold shear cutter and other cutting tools, widely used in metal/paper/plastic/food processing industry and machinery manufacturing industry.
In the production process of LION METAL sheet, Cross rolling process is adopted to give full play to the advantage of large deformation rate. Then vacuum annealing is carried out in a protective atmosphere to avoid decarbonization and restore the superplasticity of the steel. Finally, cold rolling was carried out to obtain uniformly distributed and fine carbide, and the thickness tolerance, plate shape and surface quality of the plate were controlled in the best way.
