Inconel 625LCF

INCONEL ® alloy 625LCF (UNS N06626 / W. Nr. 2.4856) was developed as a fatigue resistant, bellows quality version of INCONEL alloy 625. Alloying, melting and processing are designed and controlled to provide a sheet product with optimum resistance to low cycle and thermal fatigue at up to 1200°F (650°C). The alloy offers a high level of performance in aircraft exhaust and automotive flexible coupling bellows, expansion joints in process or transport piping, and other applications involving resistance to low cycle or thermal fatigue.
