4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components.

For example, axles, shafts, bolts, gears, and other applications.

Similar to alloy grade AISI 4130 chrome moly alloy steel but with slightly higher carbon content.

The higher carbon content of 4140 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steel.

However, it does have inferior weldability characteristics.

Features and Applications:

This steel has good strength, good toughness, high hardenability, good workability, small processing deformation, quite good fatigue resistance, small deformation during quenching, and high creep strength and durable strength at high temperature.

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines, etc.
