45CrNiMoVA Alloy Round Steel is a high-performance chromium-nickel-molybdenum-vanadium alloy steel known for its excellent strength, toughness, hardenability, and fatigue resistance. Produced through advanced hot rolling processes, this alloy round bar is widely used in heavy-duty mechanical components, aerospace structures, military equipment, and high-stress industrial applications.
With a hot rolled diameter range from 10 mm to 350 mm, 45CrNiMoVA alloy round steel offers excellent versatility for machining, forging, and heat treatment. The balanced alloy composition ensures superior mechanical properties, making it an ideal material for components that require high reliability under extreme working conditions.
Excellent high strength and toughness combination
Superior hardenability and deep hardening capability
Outstanding fatigue resistance and impact performance
Good wear resistance and thermal stability
Reliable performance under high load and high stress
Suitable for quenching, tempering, and surface hardening
The chemical composition of 45CrNiMoVA alloy steel is carefully controlled to ensure consistent performance and quality. The addition of chromium, nickel, molybdenum, and vanadium significantly improves strength, toughness, and resistance to fatigue and wear.
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.42 – 0.49 |
| Silicon (Si) | ≤ 0.40 |
| Manganese (Mn) | 0.50 – 0.80 |
| Chromium (Cr) | 0.90 – 1.20 |
| Nickel (Ni) | 1.40 – 1.70 |
| Molybdenum (Mo) | 0.15 – 0.25 |
| Vanadium (V) | 0.05 – 0.12 |
| Phosphorus (P) | ≤ 0.025 |
| Sulfur (S) | ≤ 0.025 |
After appropriate heat treatment (quenching and tempering), 45CrNiMoVA alloy round steel exhibits excellent mechanical properties suitable for demanding structural and mechanical applications.
| Property | Typical Value |
|---|---|
| Tensile Strength | ≥ 980 MPa |
| Yield Strength | ≥ 835 MPa |
| Elongation | ≥ 12% |
| Reduction of Area | ≥ 45% |
| Impact Toughness (Charpy V) | ≥ 63 J |
| Hardness (HB) | 285 – 341 |
Note: Mechanical properties may vary depending on heat treatment and section size.
45CrNiMoVA alloy round steel is available in a wide range of diameters to meet different application requirements.

| Annealing | 830 – 860 | Improve machinability |
| Quenching | 850 – 880 | Oil quenching |
| Tempering | 540 – 680 | Achieve optimal strength and toughness |
After quenching and tempering, the steel achieves a refined microstructure with excellent mechanical stability.
Thanks to its outstanding mechanical properties, 45CrNiMoVA alloy round steel is widely used in industries that demand high strength, durability, and reliability.
Aircraft landing gear components
Heavy-duty shafts and spindles
Gears and transmission parts
High-strength bolts and fasteners
Military equipment and weapon components
Forged dies and molds
Oil and gas drilling tools
Large mechanical structural parts
Compared with standard alloy steels such as 42CrMo or 40Cr, 45CrNiMoVA alloy steel offers superior comprehensive performance.
| Property | 45CrNiMoVA | 42CrMo |
|---|---|---|
| Strength | Higher | Medium |
| Toughness | Excellent | Good |
| Hardenability | Excellent | Good |
| Fatigue Resistance | Excellent | Medium |
| Impact Performance | Excellent | Good |
