What are the commonly used die steels? What are the differences between different steels?

What is the difference between NAK80 and S136?

What are the characteristics of NAK80?

If the mold core uses H13, what material is used for the inclined top, and why?

Commonly used die steel: P20, 718, 718H, S136, S136H, NAK80, NAK55, 738, 738H, S55C, H13, SKD, alloy beryllium copper, DF2, 8407, 2311 NAK80 does not require heat treatment, pre-hardened steel, the hardness is more than HRC30 , Good mirror effect, good electrical discharge machining, and better weldability.

Suitable for electrodes and polishing molds, NAK80 polishing material has obvious grain lines.

S136 needs heat treatment, hardness HRC48-52, high mirror finish, good polishing performance, suitable for PVC, PP, EP, PC, PMMA.

If the mold core uses H13, the inclined top uses DF2.
