Common Heat Treatments That Use Industrial Ovens & Furnaces

Heat treatment is a controlled process of heating and cooling materials in order to improve its properties, performance, and strength typically made up of three main steps. Firstly heating the metal to a specific temperature, soaking or maintaining the specific temperature for a certain amount of time, and cooling to a suitable rate following prescribed methods.

There are seven main techniques used for the heat treatment of materials, and all affect material in different way. These techniques are:

  1. Normalising
  2. Annealing
  3. Tempering
  4. Hardening
  5. Ageing
  6. Stress Relieving
  7. Carburisation
