Double-Loop Electrochemical Potentiokinetic Reactivation Test For Precipitation Hardened Nickel Alloy UNS N07725

Product Number: 51321-16793-SG

Precipitation hardened (PH) nickel alloy UNS N07725 used in oil and gas subsea service have experienced several brittle fractures linked to hydrogen embrittlement (HE). The alloy’s susceptibility to cracking was associated with the precipitation of a Cr- and Mo-rich phase at grain boundaries (GBs). Since the failed components were compliant with the current standards, developing a new quality control test capable of distinguish susceptible microstructures became a priority for the oil and gas industry.
