3J01 alloy has the characteristics of high strength, high elastic modulus, small elastic aftereffect and hysteresis, weak magnetism, good corrosion resistance and thermal stability, and can work under higher temperature, greater stress or corrosive media conditions.
Used to manufacture all kinds of aeronautical elastic sensitive elements and parts resistant to nitric acid or other corrosive media, such as film boxes, diaphragms, bellows, transfer rods, baffles and other elastic structures.
