| Molybdenum (Mo) | 5.0 – 7.0 |
| Nickel (Ni) | ≤ 1.0 |
| Iron (Fe) | ≤ 0.75 |
| Manganese (Mn) | ≤ 1.0 |
| Silicon (Si) | ≤ 1.0 |
| Carbon (C) | ≤ 0.35 |
| Nitrogen (N) | ≤ 0.25 |
Composition meets ASTM F1537 and ISO 5832-12 requirements, ensuring high corrosion resistance and mechanical consistency.
🔹 Mechanical Properties
| Property | Value |
|---|---|
| Ultimate Tensile Strength | ≥ 1000 MPa |
| 0.2% Yield Strength | ≥ 750 MPa |
| Elongation | ≥ 8% |
| Hardness | 250 – 350 HBW |
| Modulus of Elasticity | ~ 210 GPa |
These properties make ASTM F1537 CoCrMo Bar ideal for applications where high strength, fatigue resistance, and dimensional stability are critical.
