What steel is good for red stamping die?

8566 die steel with red stamping copper nuts can be used for red stamping more than 200,000 products.

Mr. Su, who punched copper nuts, replied that the wear resistance of 8566 die steel is twice that of HD.

Mr. Suzhou Wan is a red perforated copper nut. That is, the copper bar is heated to more than 1000 degrees with a high frequency machine, and the copper is hot washed. In the past, the hardness of HRC52-55 was achieved by H 13, HD, and the die collapsed after stamping. It is easy to crack when using tungsten steel as mold. I want to find a die steel with heat resistance, wear resistance and hardness.

After telephone communication with Mr. Wan, it is suggested that Mr. Wan use 8566 die steel. Because 8566 has good high temperature resistance, its high temperature red hardness is the same as that of high speed steel SKH-9. Working in high temperature environment can keep high hardness for a long time. The toughness is 4 times that of SKH-9 and 2 times that of d 2, which can ensure that the punch material will not crack. The hardness of 8566 is HRC58-60, and it has enough wear resistance to meet the long-term use of punch materials.

Some time ago, Mr. Wan said: Now 8566 die steel has just been used, and the effect is not bad. I will be happy if I can hit hundreds of thousands!

Visiting again today, Mr. Wan said: More than 200,000 molds have been punched, and the molds are still in use. I feel that the wear resistance of 8566 is much better than that of HD. The same hardness is HRC58-60 and 8566 is more than twice that of HD. The use effect is beyond my imagination, and I am ready to import it in batches.
