3J1
3J1 is an iron-nickel-chromium austenite precipitation-strengthened high elastic alloy. After solution treatment, it has good plasticity, low hardness and is easy to process and shape. After solid solution or cold strain aging treatment, high mechanical properties and elastic properties are obtained. The 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 be used under high temperature, large stress or Work under corrosive media conditions. 3J1 can work below 250℃ and can also be used at low temperatures (such as nearly -200℃).
