* The proper drawing range and time cycles should be determined by experiment calculated to develop those properties best suited for intended end usage.

Special Note - These temperature ranges and their resultant values are given as information only and not to be followed without experimentation. However, as these steels are held to close uniformity tolerances little difficulty should be experienced.
