Product Description and Application

3J21 is a Co-Cr-Ni-Mo high-elastic alloy, which belongs to the deformation-strengthening cobalt-based alloy, has good plasticity in the solid-soluble state, is easy to process, and can obtain high mechanical and elastic properties after cold processing and aging treatment at large strain rate. However, after solution treatment, the alloy can no longer be strengthened by aging treatment. Only after processing with a large strain rate can aging treatment produce a strengthening effect. Density of 3J21: 8.3g/cm3 2. performance, high strength, G hardness, high elastic limit, G energy storage ratio, high fatigue strength, elastic hysteresis, small after-effect, non-magnetic, good abrasion resistance, and excellent impact resistance. It can work at low and high temperatures up to 400°C.
