The 3J22 High-Durability Elastic Alloy Bar, also known as Co40CrNiMo, is a cobalt-based alloy designed for harsh environment applications. Its composition provides superelasticity, high strength, and exceptional corrosion resistance against saline conditions and high-temperature oxidation. Processed through cold-drawing and heat treatment, this bar offers a high strength-to-weight ratio and performs reliably from -60°C to +250°C. With a low thermal expansion coefficient (10–12 × 10⁻⁶/°C), density of ~8.3 g/cm³, and electrical resistivity of ~1.0 μΩ·m, it’s ideal for demanding applications.
We provide 3J22 alloy bars in various sizes and can customize compositions to meet your specific requirements, ensuring they’re ready for your harsh environment projects.
| Grades | Density (g/cm³) | Electrical Resistivity (10⁻⁶ Ω·cm) | Thermal Conductivity (W/m·K) | Modulus of Elasticity (GPa) | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation at Break (%) | Elastic Limit (MPa) | Fatigue Life (cycles) | Working Temperature Range (°C) | Temperature Coefficient |
| 8.1 | 80 | 11 | 144 | 800 | 1000 | 10 | 800 | >10⁷ | -60 to 200 | Extremely low temperature coefficient of elasticity | |
| 8.3 | 120 | 40 | 125 | 300 | 600 | 20 | 300 | >10⁷ | -40 to 150 | Elasticity remains constant with minimal temperature sensitivity | |
| 8.2 | 100 | 15 | 180 | 1100 | 1400 | 5 | 1100 | >10⁶ | -200 to 500 | Maintains high strength even at elevated temperatures |
