    Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by...

    The ASM Heat Treater's Guide has a hardness vs. tempering temperature chart but my version does not show any time reference. What time are you looking for?
    Anywhere between 2 and 72 hours will work. Another thing I forgot to mention was that is the 4140 material air cooled instead of quenched
    Here you go. it is on page 148 http://www.akronsteeltreating.com/images/ast-book.... As for the time: 2 hours at temperature. As for cooling from tempering temperture: Air cooled is best. However, if it is not complex geometry or very thin it can be quenched. This won't affect the microstructure but will induce some residual stresses. Design for RELIABILITY, manufacturability, and maintainability

    1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use. 3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400°F.

    What is 4140 steel?
    What is 4140 steel?
    4140 alloy steel is a low alloy steel that contains chromium, molybdenum, and manganese. Because it contains chromium and molybdenum, it is sometimes referred to as chromoly steel. It has high fatigue strength, excellent strength to weight ratio, is abrasion and impact resistant, has good ductility, and has excellent torsional strength.
