Product Description

3J21 Superelastic Alloy Co40CrNiMo Rod Diameter 20-100mm


3J21 Superelastic Alloy Rod Diameter 20-100mm


Xun Shi New Materials Co Ltd supplies 3J21 alloy for elastic components, 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.

The 3J21 alloy strip materials we supplied have been successfully exported to a seal manufacturer in Italy, replaced the elastic materials previously produced in France.
