  10. What 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.

  12. Tempering (metallurgy) - Wikipedia

    Quenched-steel. Tempering is most often performed on steel that has been heated above its upper critical (A 3) temperature and then quickly cooled, in a process called quenching, using methods such as immersing the hot steel in water, oil, or forced-air.

  14. What 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.
