What is 4140 Round Bar?
4140 Round Bar is a chromium-molybdenum alloy steel round bar commonly identified by AISI 4140, SAE 4140 and UNS G41400. It is a medium-carbon alloy steel developed for applications requiring a useful combination of tensile strength, toughness, hardenability and wear resistance.
The addition of chromium and molybdenum improves the hardenability and mechanical performance of the steel. Appropriate heat treatment can produce different combinations of hardness, strength and toughness depending on the intended application.
4140 Round Bars are commonly machined into shafts, gears, axles, pins, spindles, rollers, studs, crankshafts and other engineering components. They can be processed through turning, drilling, milling, threading and grinding using suitable machining parameters.
4140 is also commonly associated with EN19 and 42CrMo4 / DIN 1.7225. However, grade equivalence should always be verified against the applicable standard, chemical composition, mechanical properties and customer specification.
Advantages of 4140 Round Bars
4140 Alloy Steel Round Bars are widely selected for demanding mechanical applications because they provide a balanced combination of strength, toughness and hardenability.
- High Strength: Suitable for components subjected to substantial mechanical loading.
- Good Toughness: Provides a useful balance of strength and toughness after suitable heat treatment.
- Excellent Hardenability: Chromium and molybdenum contribute to hardenability through the section.
- Good Wear Resistance: Suitable heat treatment can improve resistance to mechanical wear.
- Fatigue Resistance: Suitable for components subjected to repeated mechanical stresses.
- Machinability: Can be machined into a wide variety of industrial components under appropriate conditions.
- Heat Treatment Capability: Can be supplied in different material conditions depending on the application.
