The 3J22 Cobalt-Based Elastic Alloy Bar, also known as Co40CrNiMo, is a cobalt-based alloy designed for high-temperature mechanical parts. Its composition provides superelasticity, high strength, and excellent corrosion resistance, even at temperatures up to +250°C. Processed through cold-drawing and heat treatment, this bar offers a high strength-to-weight ratio and outstanding fatigue resistance. 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 mechanical applications.
We provide 3J22 alloy bars in various sizes and can customize compositions to meet your specific requirements, ensuring they’re ready for your high-temperature projects.
