Inconel 625LCF UNS N06626 Fatigue-resistant Alloy Strip in Stock
Introduction of Inconel 625LCF
INCONEL 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.

Corrosion Resistance
INCONEL 625LCF (UNS N06626) has the same excellent corrosion resistance as INCONEL alloy 625 (UNS N06625). In mild environments such as the atmosphere, fresh and sea water, neutral salts and alkaline media, the alloy is virtually unaffected.
In more severe environments, the combination of nickel and chromium provides resistance to oxidizing chemicals and atmospheres, and the high nickel and molybdenum supply resistance to non-oxidating environments.
