109 pieces per kilogram of four copied 8566 die steel, punched 4.0 hot-rolled plate, punched 10000 times, the blade fell off piece by piece.
I received two cases today regarding the cracking of the four copied 8566 die steel. This one is Mr. Huang, whose mold is a 4.0 hot-rolled plate. He bought Kunshan 8566 die steel with a forming blade at a price of 109 yuan per kilogram, but after 10000 attempts, the blade fell off piece by piece.
He felt it was fake because he had used our Yuhui 8566 before and felt that this time it was too bad, so he came to Yuhui to buy two pieces of 8566 die steel to compare.
8566 is a proprietary anti collapse die steel from Yuhui Tool Steel, mainly used to solve mold cracking. It is not a national grade, but our company’s grade, our intellectual property, and does not have public attributes.
But now the 8566 die steel is already the “four copied” die steel that peers across the internet are copying, not only four copied 8566, but also shadow 8566; It is also a reference standard for some large steel mills, which is an unprecedented industry phenomenon.
The anti cracking performance of 8566 is 4 times that of SKH-9 and 2 times that of D2, with a hardness of 58-60HRC. It has accumulated over a thousand cases in 5 stamping conditions, 6 major materials, and 7 major fields. The punch used for cracking is 8566 die steel. In both old and new societies, anything that falls off piece by piece is definitely fake.
Many customers love to tinker and use 85668566 anti collapse steel for their molds. They have no problem with their own molds, but they feel that they are buying too expensive and insist on buying some cheaper 8566 to verify their intelligence. After falling for it, they become very angry and ask you to ship it immediately, waiting to put out the fire.
For me, this is not a bad thing. Only when the money is spent can he feel at ease. Only when he has been deceived can he be determined. When he comes, he won’t negotiate the price anymore.
The punch cracking is made of 8566 die steel, which is a double-edged sword in both old and new societies. Even those who have used it will buy it.
