    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 bytempering 4140

  25. Tempering (metallurgy) - Wikipedia

    Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. The exact temperature determines the amount of hardness tempering 4140Some results are removed in response to a notice of local law requirement. For more information, please see here.
