Are you surprised to see the relationship among SKD11, DC11, DC53, SLD and SLD8? Isn't that just some code name for die steel? What difference does it make? So let me give you a quick explanation. here.

SKD11, DC11, DC53, SLD and SLD8 are all code names of cold working mold steel materials from Japan. The original unified name is SKD11, but the code names are different because they come from different steel companies. Here we refer to DAIDO and HITACHI in Japan. DC11 and DC53 are the names of the upgraded SKD11 materials from Japan's DAIDO Company, while SLD and SLD8 are the names of the upgraded SKD11 materials from Japan's HITACHI Company. In essence, it is obtained by making some changes on the original basis, but the improved mold steel material has been improved in different degrees in terms of hardness, toughness and stress inhibition compared with the previous one, so the improved product is better than the previous one.
