Mercury Liquid Metal Embrittlement Testing of Oil and Gas Production Alloys

 Liquid metal embrittlement (LME) involves penetration of a liquid metal into a solid metal that leads to brittle fracture. A test program was established to evaluate the susceptibility of various metallic materials to LME by mercury.

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. A test program was established to evaluate the susceptibility of various metallic materials to LME by mercury. The susceptibilities of different alloys were determined using: 1) slow strain rate testing (SSRT) in mercury for screening and 2) fitness for service testing based on constant deflection testing (4-point bending) in a simulated service environment. Materials tested included 3.5% Ni steel (UNS K32018) 17-4PH (UNS S17400) and 304 stainless steel (UNS S30400). Results indicate the value of testing using both a screening and fitness for service methodology as the constant load fitness for service testing can more accurately define the stress level of LME susceptibility.

Key words: Liquid Metal Embrittlement, mercury, stainless steel, corrosion resistant alloys
