Netizen Mr. He said that DC53 die steel is used to stretch DC01 iron material. Stretching one product will cause scratches, polishing the mold will make it shiny again, and stretching again will cause scratches. What is the reason for this and what die steel should be used to solve it?
Stretching a product with a stretching mold can cause scratches, which is due to the adhesive wear of the adhesive material and also a quality issue in the smelting of die steel.
Mold steel with poor smelting quality has structural segregation, and there are a large number of microscopic and fine cracks on the structure that are invisible to the naked eye. During the stretching process, when these fine cracks come into contact with DC01 iron material, adhesive wear of the material will occur, resulting in scratches and pulling of the product.
When buying die steel, people only care about the price and compare prices, thinking that as long as the grade is correct, the performance is correct. However, the actual use effect is once again criticized.
Stretching DC01 iron material, DC53 produces scratches after stretching one product, which is caused by poor quality of DC53 die steel smelting. There are two solutions: either apply a surface coating to the current DC53 mold to cover fine cracks and eliminate mold scratches. Either replace the non stick mold steel with high-quality DC53 and stretch the iron material, which will not scratch so quickly.
The bending and shaping mold for iron pipes is made of Cr12MoV, and the product is always scratched. The master always calls for it, but using Yuhui ordered product DC53 has a much better effect, and the master no longer calls for it.
This case has once again shown me that the die steel market is very chaotic, with inferior products being sold as good, fake products being sold everywhere. Of course, this is also an opportunity. As long as you do a good job in the quality of die steel, market opportunities can be seen everywhere.
