  • 35crmo quenching and tempering steelWhat is quenched and tempered steel? - ShapeCUT

    What is quenching and tempering? Quenching and tempering are processes that strengthen and harden materials like steel and other iron-based alloys. The process of quenching or quench hardening involves heating the material and then rapidly cooling it to set the components into place as quickly as possible.

    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?

  • 35crmo quenching and tempering steelQuenching - Wikipedia

    Often, after quenching, an iron or steel alloy will be excessively hard and brittle due to an overabundance of martensite. In these cases, another heat treatment technique known as tempering is performed on the quenched material in order to increase the toughness of iron-based alloys.

    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.

  • 35crmo quenching and tempering steelWhat Is the Metallurgical Term Known as Tempering?

    Tempering is a heat treatment process that is often used to improve hardness, strength, toughness, as well as decrease brittleness in fully hardened steel. A martensitic crystal phase is formed in steel when excess carbon is trapped in the austenitic lath and quickly cooled (usually by water quenching) at a suitable rate.
