  • High Speed Steel | H13 Steel | H13 - Tool Steel | High

    Because of its excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel. Because of its high toughness and very good stability in heat treatment, H13 is also used in a variety of cold work tooling applications.

  • 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.

  • Heat Treating Quench and Temper
