Corrosion Resistance: Provides superior resistance to oxidation and various corrosive environments [3], [4].
Process:
Heat Treatment: Proper heat treatment is essential to achieve the desired mechanical properties, enhancing strength and ductility.
Cold Working: The wire can be cold worked to improve its mechanical properties before final shaping into springs.
Coiling Techniques: Special coiling techniques may be required to prevent cracking or deformation during the manufacturing process [7], [8].
Points to Pay Attention to When Making Inconel X750 Springs
Temperature Management: Ensure that the manufacturing processes do not exceed the alloy's recommended temperature limits to avoid degradation of properties.
Tool Selection: Use tools that are appropriate for working with high-strength alloys to prevent
tool wear and ensure precision.
Quality Control: Regular inspection of the springs for dimensional accuracy and mechanical properties is crucial to ensure performance in applications.
By focusing on these aspects, manufacturers can effectively utilize Inconel X750 wire to produce high-performance springs suited for demanding environments
