Product Description Product DescriptionAlloy round steels are characterised by a variety of features, notably high strength, high toughness, resistance to wear, corrosion, high and low temperatures. These features make alloy round steel excel in various industrial applications and are widely used in machinery, automotive and many other fields. 4140 alloy structural steel is a U.S. standard grade of medium-high strength alloy steel. The material has high strength, high hardenability, good toughness and quenching deformation, etc., suitable for the manufacture of locomotive traction gears, supercharger transmission gears and other high-strength forgings.1). 4140 Steel Equivalent Grades : GBDINASTMJISBSNF42CrMo1.72254140SCM440708M4042CD42). 4140 Steel Composition: GradeCSiMnCrMoPS41400.38-0.430.15-0.350.75-1.000.80-1.100.15-0.25<0.035<0.0442CrMo0.38-0.450.17-0.370.50-0.800.90-1.200.15-0.25<0.035<0.0351.72250.38-0.450.10-0.350.60-0.900.90-1.200.15-0.30<0.025<0.025SCM4400.38-0.430.15-0.350.60-0.900.90-1.200.15-0.30<0.030<0.030708M400.36-0.440.10-0.400.50-0.900.90-1.200.15-0.30<0.035<0.03542CD40.38-0.460.10-0.400.60-0.900.85-1.200.15-0.30<0.035<0.0353).
