Received consultation from netizens, stamping 2.3-thick acid washed plate, SKD11、DC53， This corner always falls off.
This product is a narrow edge sharp angle stamping with harsh working conditions, requiring the use of tool steel with good anti cracking performance. SKD11 and DC53 are both high carbon cold work mold steels with severe segregation and a large number of microscopic micro cracks that cannot be seen by the naked eye, resulting in poor anti cracking performance. When used for this narrow edge sharp angle punch, it is easy to crack.
This cruel working condition, which is prone to corner breakage, requires the use of 8566 anti collapse steel.
8566 is a proprietary anti collapse steel developed by Yuhui Tool Steel, which mainly solves the problem of mold cracking; It has accumulated over a thousand cases in 5 working conditions, 6 major materials, and 7 major fields of stamping.
The anti cracking performance of 8566 die steel is four times that of high-speed steel SKH-9 and twice that of D2, with a hardness of 58-60HRC. It can solve the cracking problem that cannot be solved by high hardness mold steels such as D2, DC53, and SKH-9; Especially in harsh working conditions such as stainless steel stamping, sharp corner stamping, narrow edge stamping, and even punch widths smaller than the plate thickness, with stamping ratios less than 1:1, cracking that cannot be solved by conventional mold steel is solved by using 8566 die steel.
Mr. Meng stamped 2.5mm high-strength plates, but the sharp corners of R1 always broke, and the punches of Cr12MoV, DC53, and SKH-9 always broke corners, causing the molds to break. The speed of mold repair cannot keep up with the speed of punch cracking, and the punching machine cannot be opened.
Mr. Meng stamped 2.5mm high-strength steel, which is also the sharp corner of R1. The material is much thicker and harder than the 2.3mm pickled plate of the netizen, and it is also prone to corner collapse. However, using 8566 anti collapse steel solved the problem, so I also recommend him to use 8566 anti collapse steel.
The use of 8566 die steel for punch cracking is a double-edged sword in both old and new societies.
