 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.
