Mercury is a naturally occurring component present in varying concentrations in natural gas fields all over the world. Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture. In assessing the design of a production facility a test program was established to evaluate the susceptibility of various metallic materials to LME by mercury. The susceptibilities of the alloys were determined using: 1) slow strain rate testing (SSRT) in mercury for screening and 2) subsequent fitness for service testing based on constant load testing (4-point bending) in a simulated service environment. Materials tested included duplex 2205 alloy 625 Alloy 400 316L stainless MP35N Al5083 aluminum alloy and welded alloy 625. Results from these tests indicate that Alloy 400 and Al5083 showed significant LME susceptibility with an average time-to-failure ratio of 0.60 during slow strain rate screening tests. Constant load fitness for service testing resulted in no significant LME cracking in duplex 2205 alloy 625 316L stainless welded alloy 625 and alloy 400 tested at 100% of actual yield strength in a simulated Hg-containing service environment.
