These
are medium-carbon steels. In their production, special controls are used for chemical
composition, heating, rolling, surface preparation, etc. As a result of this careful processing, these bars are suitable for
applications involving forging, heat treating, cold drawing, and machining.

These grades are essentially water hardening steels but may be quenched in oil. The recommended quenching temperatures are 1550° F for water and 1575° F for oil. A wide range of mechanical properties can be obtained by tempering at different temperatures between 700° and 1300° F. Tempering in the range from 500° to 700° F should be avoided.
