51318-11212-Rapid Screening of Additive Manufactured Specimens for Sour Testing: Orientation and Surface Effects

Mechanical and electrochemical rapid screening techniques for UNS(4) S17400 (AM) material were evaluated in comparison to sour tests of the same materials. Effects of the as-deposited surface were explored, in addition to the influence of build orientation.

Additive Manufacturing (AM) presents new opportunities and potential pitfalls to the Oil and Gas

Market. Currently, additive manufacturing is not a production route addressed by ANSI(1)/NACE(2) MR0175-2015 / ISO(3) 15156-31 (NACE MR0175). To utilize the benefits of AM in sour service environments, new qualification and materials testing requirements will be necessary. In this work, mechanical and electrochemical rapid screening techniques for UNS(4) S17400 (AM) material were evaluated in comparison to sour tests of the same materials The effects of the as-deposited surface were explored, in addition to the influence of build orientation. The overall goals were to determine the sulfide stress cracking (SSC) resistance via NACE TM01772 Method A testing relative to a particular AM material and heat treatment, and then to see how that service limit was impacted by build orientation. The data generated were compared to corrosion testing data in the literature on UNS S17400, particularly with previous work contained in NACE CORROSION Conference Paper C2017-96673 on UNS S17400 AM. 

Key words: Additive manufacturing, SSC resistance, NACE MR0175 qualification, UNS S17400
