  • Difference Between Annealing and Tempering Metal

    May 09 2016 · The difference between annealing and tempering comes down to how it is treated. Annealing involves heating steel to a specified temperature and then cooling at a The difference between annealing and tempering comes down to how it is treated. Annealing involves heating steel to a specified temperature and then cooling at a very slow and controlled rate whereas tempering involves heating the metal to a precise temperature below the critical point and is often done in air vacuum or inert atmospheres.
