What is Decarb-Free Tool Steel?

Decarb-free (DCF) tool steel is material that has been ground top and bottom and is oversized to finish on the thickness or diameter.  DCF offers excellent wear resistance, combined with good deep hardening characteristics. Its ability to show low distortion or movement in heat treatment makes this material an excellent product for many tool room applications where size stability is critical.
