Nickel-based high-temperature alloy machined parts

Nickel-based alloys: High-end special alloys with nickel (Ni) as the base material (nickel content ≥50%), and alloying elements such as chromium, molybdenum, tungsten, aluminum, titanium, cobalt, and copper added. They possess excellent comprehensive performance under extreme conditions of high temperature, strong corrosion, high pressure, and strong oxidation/reduction.

Core Characteristics:
High Temperature Resistance: High high-temperature strength, creep resistance, thermal fatigue resistance, and high-temperature oxidation resistance; can be used for long-term service at 600–1200℃.
Strong Corrosion Resistance: Resistant to strong acids, strong alkalis, seawater, chloride ions, pitting corrosion, crevice corrosion, and stress corrosion.
Stable Performance: Stable microstructure under alternating hot and cold conditions; excellent wear resistance, radiation resistance, and weldability.
Comparative Advantages: Performance far exceeds that of 304/316 stainless steel and carbon steel; an irreplaceable material for extreme conditions.
