Alloy 625 LCF® | HP® | 2.4856 - Data sheet
UNS N06626 | AMS 5879 | 2.4856
INCONEL Alloy 625LCF and ATI 625HP are variants of Alloy 625 with the same basic chemistry but with tighter control of the C, Si, and N content to ensure lower values, which is achieved through vacuum induction melting. When combined with careful thermal and mechanical processing, it yields a fine-grained microstructure optimized for formability and fatigue resistance. These variants offer up to 100 times the lifespan of a conventional Alloy 625.
