Product Description
A nickel-chromium-molybdenum alloy that was developed as a fatigue-resistant bellows-quality version of INCONEL alloy 625. Alloying, melting and processing of this alloy are specially designed and controlled to provide a sheet product with optimum resistance to low-cycle and thermal fatigue at temperatures up to 1200°F (650°C).
Used in Aircraft exhaust and automotive flexible coupling bellows and expansion joints in various types of process or transport piping.
