Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel.
ABRAMS STEEL GUIDEAISI/SAE 4140+QT:Heat-treatable steel (tempered condition) that can be used for a wide range of applications with a high degree of strength and toughness. Often used for demanding applications in automotive engineering. In quenched and tempered condition it is used in machine construction.
AISI 4140 AISI 4140 Q+T Round Bar Sales Promotion after AISI alloy 4140 steel bar, plate and square can be hardened by cold working, or heating and quenching. SAE 4140 alloy steel is usually supplied ready heat treated to hardness in 18-22 HRC.
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 tensile strength of 130 ksi can be achieved by

China Alloy Steel Round Bar (AISI 4140) - China Aisi 4140 AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications. Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content.
How To Weld 4140 Steel WELDING ANSWERSAISI 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel. The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a
Jul 24, 2019 · 4140 is very nice to machine and the pre-hardened version is a real winner for surface finish. Try 400 fpm for roughing, .020" feed and as big a DOC as you have horsepower for. I was doing .19" DOC in a 3" diameter pre-hardened bar while testing a new Iscar tool (.032 nose rad) and that was about the limit for my 10hp spindle.
