Temper

In one of our range of air circulating tempering furnaces.

All components in the hardened condition are too hard and too brittle for their designed purpose and must be tempered by reheating the component at a lower temperature to reduce the as hardened condition to the desired hardness or strength value.

The temperature, usually between 150°c and 550°c, and time given to the component are again critical to allow the temperature to equalize fully followed by slow cooling to room temperature.

Some materials used dictate a double and sometimes triple temper whereby we have to repeat the tempering process to obtain the required structure and hardness.
