Brief introduction:
3J1's iron-nickel-chromium austenitic precipitation strengthened high elasticity alloy. After solution treatment, it has good plasticity and low hardness,so it's easy to process and mold. After solid solution or cold strain aging treatment,it gains high mechanical and elastic properties.
It is mainly used for manufacturing various aviation elastic sensitive elements and parts resistant to nitric acid or other corrosive media, such as bellows, diaphragms, bellows, transfer rods, baffles and other elastic structural members.
