Product Description Sncm220 21nicrmo2 1.6523 8620 Hot Forged Rolled Steel Round Bar1: 4140 steel introduction 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. The higher carbon content of AISI 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability characteristics.. 2: 4140 Steel equivalentCountryJapanGermanyBritainUSAChinaAustraliaStandardJIS G4105DIN 17200BS970ASTM A29GB/T 3077AS 1444GradeSCM44042CrMo4/1.7225EN19/709M40414042CrMo4140 3: 4140 steel chemical compositionGradeCSiMnPSCrMoNi41400.38-0.430.15-0.350.75-1.00.0350.040.8-1.10.15-0.25 42CrMo40.38-0.450.40.6-0.90.0350.0350.9-1.20.15-0.3 EN190.35-0.450.1-0.350.5-0.80.050.050.9-1.50.2-0.4 SCM4400.38-0.430.15-0.350.6-0.850.030.030.9-1.20.15-0.3 4: 4140 steel mechanical properties The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT.
