Core Advantages
Exceptional High Temperature Resistance: Capable of sustained operation at temperatures up to 550°C and short-term exposure to temperatures exceeding 600°C. Exhibits no significant stress relaxation in high-temperature environments, maintains stable stiffness, and does not suffer from elastic decay or deformation failure due to rising temperatures, making it ideal for continuous operation under high temperature conditions.
Superior Corrosion and Aging Resistance: The high nickel chromium alloy matrix resists acid and alkali corrosion, salt spray, oxidation, and sulfidation. It can be used long-term in harsh corrosive environments such as humid, chemical, marine, and oil and gas settings. Its resistance to aging and oxidation far exceeds that of 304 and 316 stainless steel spring wire, extending service life by more than three times.
Ultra High Strength and Fatigue Resistance: Through precipitation hardening treatment, it exhibits excellent tensile and yield strengths, with a dense and uniform microstructure free of porosity and inclusions. It is resistant to fatigue fracture under high-frequency repetitive deformation and offers exceptional elastic stability, making it suitable for high-frequency, high-load precision elastic components.
Low Stress Relaxation and High Dimensional Accuracy: Precision cold-drawn forming ensures strictly controlled wire diameter tolerances, with a smooth surface free of burrs and scratches; a special tempering process significantly reduces internal stress, resulting in minimal deformation under long-term loads and ensuring lasting stability in component dimensions and elastic precision.
Stable and Reliable Overall Performance: It offers excellent cold and hot working properties as well as weldability; it does not fracture due to brittleness in low temperature environments, and its mechanical properties do not degrade. It is suitable for complex operating conditions involving alternating high and low temperatures. Certified under an aerospace grade quality management system, it delivers exceptional consistency and reliability.
