Brief introduction

3J1 alloy is an iron-nickel-chromium austenite precipitation enhanced high elasticity alloy. After solution treatment has good ductility, low hardness, easy processing. After solution or cold strain aging treatment, access to high mechanical properties and elastic properties.

This kind of alloy has the characteristics of high strength, high modulus of elasticity, small elasticity and hysteresis, weak magnetic property, good corrosion resistance and thermal stability. It can work at higher temperature and larger stress Or corrosive media conditions. 3J1 can work below 250 ℃. Such alloys can also be used at low temperatures (such as near -200 ℃).
