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 used extensively for engineering components where strength, toughness and hardenability are important.
The addition of chromium and molybdenum contributes to hardenability and mechanical performance. Depending on the material condition and heat-treatment process, 4140 can provide different combinations of hardness, tensile strength and toughness.
4140 Round Bars can be machined into shafts, gears, pins, axles, spindles, rollers, studs, crankshafts and other mechanically loaded components. Suitable machining operations include turning, drilling, milling, threading and grinding.
4140 is commonly associated with EN19 and 42CrMo4 / DIN 1.7225. Exact grade equivalence should always be confirmed 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 engineering applications because they provide a useful combination 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.
- Wear Resistance: Suitable heat treatment can improve resistance to mechanical wear.
- Fatigue Performance: Suitable for components subjected to repeated mechanical stresses.
- Machinability: Can be machined into a variety of engineering components under appropriate machining conditions.
- Heat Treatment Capability: Can be supplied in different material conditions according to application requirements.
