CarTech D3 tool steel is an oil hardening, high-chromium tool and die steel possessing extreme wear resistance. It hardens with very little change in size or shape. CarTech D3 tool steel is deep hardening and exhibits very high compressive strength. Because of its high percentage of chromium, it displays mild corrosion resisting properties when hardened.

Applications:
CarTech D3 tool steel has been used for tools requiring a combination of hardening accuracy and safety with maximum wear resistance and greatest possible production.

1. Use it for tools requiring exceptionally long life or for work on abrasive materials such as:

Spindles
Hobs
Cold rolls
Slitting cutters
Master tools
Blanking dies
Forming dies
Lamination dies

2. Use it for tools that must hold size and shape more accurately than water hardening steels or where the shape makes water quenching dangerous such as:

Thread gauges
Spinning tools
Extrusion dies
Intricate punches
Blanking dies
Trimming dies
Plungers
