4140 forging
4140 forging has a high strength level while still maintaining good toughness and ductility. This makes 4140 forging an ideal choice for applications that require a balance of strength and toughness.
4140 forging is used extensively in most industry sectors for a wide range of applications which requires high strength with good toughness and ductility. The typical usages of 4140 forging are 4140 shaft forging, 4140 forged rod, 4140 motor shaft forging, 4140 hydraulic shaft etc.
4140 forging applications:
4140 forging is used extensively in most industry sectors for a wide range of applications such as:
adapters, arbors, axle shafts, bolts, crankshafts, connection rods, chuck bodies, collets, conveyor pins & rolls, ejector pins, forks, gears, guide rods, hydraulic shafts & parts, lathe spindles, logging parts, milling spindles, motor shafts, nuts, pinch bars, pins various, pinions, pump shafts, rams, sockets, spindles, sprockets, studs, tool holders, torsion bars, worms etc.
4140 forging chemical composition:
The combination of these elements, particularly chromium and molybdenum, contributes to the alloy’s high tensile strength, hardness, resistance to wear, and hardenability. The carbon content also plays the biggest role in the hardenability of the steel.
forged 4140 steel advantages
4140 forged steel are alloy steel forgings containing high levels of chromium and molybdenum. 4140 alloy steel forgings have the characteristics of high strength, good hardenability, good toughness, and small deformation during quenching.
- High strength: The strength of 4140 steel forgings belongs to high-strength alloy steel forgings, with high yield strength and high tensile strength.
- Good hardenability: After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
- Good toughness: 4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
- Small deformation during quenching: 4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
- High high-temperature creep strength and endurance strength: 4140 steel forgings have good strength and endurance performance at high temperatures.

What Are the Key Properties of 4140 Pre-Hardened Steel?
The key properties of 4140 pre-hardened steel are as follows:
- Superior toughness
- Good wear resistance
- Good ductility
- High tensile strength
- Good machinability
- Good heat resistance
- High fatigue resistance
4140 steel can be heat-treated to a high strength level while still maintaining good toughness and ductility. This makes 4140 alloy steel forgings an ideal choice for applications that require a balance of strength and toughness.
