 a. Heat treatment abbreviations are as follows: HR - hot rolled; A - annealed; CD - cold drawn;  N - normalized; QT - quenched & tempered.
 b. Coated carbide tool material grades are designated by an additional prefix letter C, to distinguish it from the Industry Code system for
 uncoated carbide tools.
