Product description and application

3J21 is a Co-Cr-Ni-Mo high elastic alloy. It is a deformation-strengthened cobalt-based alloy. It has good plasticity in the solid solution state and is easy to process. After high strain rate cold working and aging treatment, high mechanical properties can be obtained. performance and elastic properties. However, after solution treatment, the alloy can no longer be strengthened by aging treatment. Only after processing at a large strain rate, aging treatment can 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 and small aftereffects Non-magnetic anti-wear Good impact resistance and excellent corrosion resistance. It can work under low and high temperature conditions, with high temperatures up to 400°C.
