High temperature behaviour of H13 steel

In this study, an investigation was carried out in order to determine the effect of annealing temperature on the mechanical properties of H13 steel. Heat treatments were applied on samples at different temperatures in both, the as-received and as-quenched conditions. In order to indicate the effect of heat treatment temperature, hardness measurements and tensile tests were performed at all chosen temperatures. At relatively high temperatures the mechanical properties of the H13 steel have been diminished considerably.
