What is 4140 Round Bar?
4140 Round Bar is a solid circular chromium- molybdenum alloy steel product. It is commonly specified as AISI 4140, SAE 4140 and UNS G41400.
The grade is known for its useful combination of high strength, toughness and hardenability. Depending on the required application, 4140 Round Bars can be supplied in suitable material conditions such as annealed, normalized, quenched and tempered or hardened and tempered.
4140 is also commonly associated with engineering designations such as EN19, 42CrMo4 and DIN 1.7225. However, the exact equivalence should always be confirmed against the required chemical composition, mechanical properties and applicable standard.
The circular shape of the bar makes it suitable for turning, drilling, milling, threading, grinding and other machining operations. It can be converted into shafts, gears, axles, pins, spindles, rollers, studs and other engineering components.
Why Choose 4140 Round Bars?
4140 alloy steel is widely used where components must withstand mechanical loads, impact, torsional forces and repeated stress. Chromium and molybdenum contribute to the material's hardenability, while suitable heat treatment can provide a balance of strength, hardness and toughness.
- High Strength: Suitable for heavily loaded mechanical components.
- Good Toughness: Provides a useful combination of strength and toughness after appropriate heat treatment.
- Excellent Hardenability: Chromium and molybdenum contribute to good hardenability.
- Good Wear Resistance: Suitable heat treatment can improve resistance to mechanical wear.
- Good Fatigue Performance: Suitable for components exposed to repeated mechanical loading.
- Machinability: Suitable material conditions can be machined into different engineering components.
- Heat Treatment Capability: Can be supplied in different conditions according to application requirements.
