Heat treaters may perform the following tasks:

  • load items to be treated into the furnace and bring the metal to a specified temperature
  • use computer-controlled furnaces
  • use new technologies, such as advanced vacuum furnaces
  • check all gauges and controls during treatment to make sure they are working correctly
  • harden metal by heating it to the required temperatures (this varies with different metals) and dipping it in oil, gas, water, brine or other solutions
  • surface-harden metal components to improve their resistance to wear and abrasion
  • use special instruments to test the hardness and mechanical properties of treated metals.
