INCONEL® Alloy 625LCF®

2.4856  /  UNS N06625 / N06626

A nickel-chromium-molybdenum alloy that was developed to have excellent fatigue resistance especially for bellows applications.  As with the widely known alloy 625 it has excellent resistance to oxidation and corrosion in a range of environments and conditions.  Alloy 625 LCF has a restricted composition and melting and processing of this alloy is closely controlled to provide a sheet product with optimum resistance to low-cycle and thermal fatigue at temperatures up to 650°C (1200°F). It finds application for flexible coupling bellows in both the automotive and aerospace sectors and expansion joints in various types of process piping.
