K107 Tool Steel

What is K107 tool steel?

K107 is a die steel in accordance with the Austrian Bohler standard and belongs to the category of deep-hardened oil-quenched tool steel. Compared with conventional Cr12 or K100 steel, K107 has a higher carbon content and an excellent hardening depth, making it more suitable for cold working scenarios where wear resistance and pressure bearing capacity are required to be more extreme.

K107 steel not only can achieve a hardness of over 60 HRC through heat treatment, but also maintains high hardness while still having good impact toughness. It is particularly suitable for mold designs that require high wear resistance and the ability to withstand heavy impact loads.
