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 widely used in engineering applications where strength, toughness and hardenability are important.
The chromium and molybdenum content contributes to the hardenability and mechanical performance of the steel. Depending on the material condition and heat treatment, 4140 can achieve different combinations of hardness, strength and toughness.
4140 Round Bars can be machined into shafts, gears, pins, axles, spindles, rollers, studs, crankshafts and other engineering components. They can be processed through turning, drilling, milling, threading and grinding using suitable machining conditions.
4140 is also commonly associated with EN19 and 42CrMo4 / DIN 1.7225. Exact grade equivalence should always be confirmed against the applicable standard, chemical composition and mechanical-property requirements.
Advantages of 4140 Round Bars
4140 Alloy Steel Round Bars are selected for demanding engineering applications because they provide a useful balance of strength, toughness, hardenability and wear resistance.
- High Strength: Suitable for components subjected to substantial mechanical loads.
- Good Toughness: Provides a useful balance between strength and toughness after suitable heat treatment.
- Good Hardenability: Chromium and molybdenum contribute to hardenability through the material section.
- Good Wear Resistance: Suitable heat treatment can improve resistance to mechanical wear.
- Fatigue Performance: Suitable for components subjected to repeated mechanical loading.
- Machinability: Can be machined into various engineering components under suitable material and machining conditions.
- Heat Treatment Capability: Can be supplied in different material conditions according to the application requirement.
