Introduction to 18Cr2Ni4WA Alloy Steel Round Bar
18Cr2Ni4WA is a high-strength, high-durability alloy steel commonly used in various structural applications. The alloy composition includes Chromium (Cr), Nickel (Ni), and Molybdenum (Mo), which endow the steel with exceptional mechanical properties. Hot rolled and forged 18Cr2Ni4WA alloy steel round bars with diameters ranging from 20mm to 300mm are widely utilized in industries requiring robust materials capable of withstanding heavy mechanical stress, corrosion, and high-temperature environments.
This alloy steel is particularly renowned for its excellent performance in applications such as machinery manufacturing, heavy-duty equipment, automotive components, and aerospace engineering. The steel is produced through advanced forging and hot rolling processes, which significantly enhance its strength, fatigue resistance, and overall reliability.
Chemical Composition
The key elements that make up the 18Cr2Ni4WA alloy steel are:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.18 - 0.22 |
| Chromium (Cr) | 1.8 - 2.2 |
| Nickel (Ni) | 3.8 - 4.2 |
| Molybdenum (Mo) | 0.2 - 0.4 |
| Silicon (Si) | 0.3 - 0.6 |
| Manganese (Mn) | 0.5 - 0.8 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Tungsten (W) | 0.4 - 0.7 |
This unique combination of alloying elements provides excellent toughness, wear resistance, and high-temperature stability.
Mechanical Properties
The mechanical properties of 18Cr2Ni4WA alloy steel round bars can be summarized as follows:
| Property | Value |
|---|---|
| Tensile Strength | 800 - 1000 MPa |
| Yield Strength | 650 - 850 MPa |
| Elongation | ≥ 15% |
| Hardness (HB) | 250 - 300 |
| Impact Toughness | ≥ 30 J at -20°C |
| Modulus of Elasticity | 200 GPa |
These mechanical properties ensure that the 18Cr2Ni4WA alloy steel is capable of withstanding high levels of stress and wear while maintaining structural integrity under extreme conditions. The tensile strength, yield strength, and impact toughness make it ideal for use in critical structural and engineering applications where reliability is essential.
