Heat Treating
  • A process to achieve the desired balance between hardness and resilience for the intended purpose of the metal. First, the steel is heated to above its austenitic temperature (around 1800°F depending on the alloy; incandescent orange, and no longer attracted by a magnet). Then, is quenched in water or oil to cool it as rapidly as possible. Now, exceptionally hard and too brittle for most applications, it is re-heated to a specific lower temperature than before and quenched again, relieving the desired amount of its hardness.
