How important is the substrate material selection?
It is most common to apply the TRD coating on the existing tool steel. However this might not be the right choice for your particular application. Finding the best material will benefit you in the long run. If you are thinking about using the TRD process on your existing tool steel there are some things you do not have to consider. They are wear resistance, anti-seizure, and corrosion because the TRD process improves all of these areas.
