High Hardness And Strength 3J21 Superelastic Alloy Wire Strip Rod

 

3J21 is a deformation reinforced cobalt-based alloy, with good plastic properties and easy to process in the solid solution state. After high strain rate cold processing and time limit treatment, 3J21 can obtain high mechanical and elastic properties, but after the solid solution treatment, the alloy can no longer be strengthened by time limit treatment.

 

Characters

3J21 has high strength, high hardness,high elasticity limit, high energy storage ratio, high fatigue strength, small elasticity lag and rear effect, non magnetic, good wear resistance, seismic and shock resistance, excellent corrosion resistance, can work at high temperature 400 °C and also can work normally at low temperature.

 

Density:8.3g/cm3

3J21 heat treatment

Elastic element: 30%~70% cold strain + 370 °C~480 °C, 2~4 hours, air cold

Axis tip: 90% cold strain + 500 °C~550 °C, 4 hours, air cold

Oxid film appears on the surface of the alloy after heat treatment, and that can be removed by alkali immersion-acid washing method.

 

The Equal grades

Elgiloy, Phynox,NAS604PH,UNS R30003(ASTM F1058),W.Nr 2.4711
