Chemical Composition (%)

Cold Work Tool Steel AISI D5 is an air hardening, high-carbon, high-chromium, tool steel that is characterized by a cobalt addition which provides unique resistance to galling and pick-up. The cobalt also imparts some resistance to tempering, which makes D5 suitable for some semi-hot work tooling applications.

Low deformation when quenching.

Good hardenability and abrasion resistance .

Good hardness and ductility.


Applications of D5 steels include thread rolling, blanking or forming dies operating at temperatures below 482°C.
