astm temper embrittlement

  • What is temper embrittlement, and how can it be controlled

    Temper embrittlement refers to the decrease in notch toughness of alloy steels when heated in, or cooled slowly through, a temperature range of 400°C to 600°C. Temper embrittlement can also occur as a result of isothermal exposure to this temperature range.Read More
