  • Quenching and tempering - tec-science

    What is the aim of quenching and tempering compared to hardening? In which three process steps can quenching and tempering be divided? Why is quenching and tempering not counted as an annealing process? Why must the steel be kept at a specific temperature for a certain time during austenitizing? What microstructural changes occur during quenching?

  • Heat Treatment for Tempering Steel Life of a Casting ...

    In tempering, a metal is reheated yet again, but now to a lower temperature than in annealing, normalizing, or quenching. Martensite is not a stable molecule in heat—it is achieved under shock—so tempering steel means destabilizing the martensite to let it start to convert to cementite and ferrite.

  • 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 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.

  • Tempering (metallurgy) - Wikipedia

    Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its ...
