    4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.

  6. AISI 4140 Alloy Steel (UNS G41400) - azom.com

    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 a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by best 4140 steel rockwell hardness

    Dec 25, 2009 · I use it as my default steel. "4140 pre hard" is from my experience RC30 and machines very nicely. It is what comes from McMaster, Enco, or MSC. I have also used "4140 Q&T" and it came through nearer RC 36. I believe Q&T has a spec with it to disclose the hardness as when I ordered it, it was available in two tensile ratings.
