NiFe Alloy 3J21 （Co40CrNiMo）

3J21

Chemical composition:

3J21 (Co40CrNiMo) alloy is a commonly used Co-based high-elastic alloy, which has good comprehensive properties such as high elasticity, high fatigue resistance, high corrosion resistance and non-magnetic properties. After deformation heat treatment of this alloy, high Excellent elastic properties, high strength, hardness, wear resistance, fatigue resistance and non-magnetic properties, high corrosion resistance in many media, certain thermal stability and low notch sensitivity. Therefore 3J21 alloy is widely used in the fields of national defense and civil industry. It is suitable for making small-section elastic components and precision devices on aerospace vehicles, such as clock springs, tension wires, shaft tips, special bearings and other elastic sensitive components. And elastic components. In order to maintain the stability of the performance of 3J21 alloy, it needs to be aged before manufacturing.

Characteristic as below：

3J21 has no magnetism, corrosion resistance, high elasticity, high strength and good fatigue resistance; 3J1 has weak magnetism, corrosion resistance, and good elasticity below 200°C; 3J53 is in the range of – 60°C~ 700°C It has a low temperature coefficient of elastic modulus, high elasticity and strength.

3J21 elastic alloy is mainly used in the following environments:

• High temperature environment: 3J21 elastic alloy has good corrosion resistance and high temperature elastic properties in high temperature environment, and can be used to manufacture high temperature springs, high temperature valve springs, etc.

• Corrosive environment: 3J21 elastic alloy has good corrosion resistance, and can be used to manufacture springs and elastic parts in corrosive environments such as chemical industry and ocean.

• Low-temperature environment: 3J21 elastic alloy has good low-temperature elastic properties, and can be used to manufacture low-temperature valve springs, low-temperature sensors, etc.

• High-stress environment: 3J21 elastic alloy has high yield strength and tensile strength, and can be used to manufacture high-stress springs and elastic parts.
