When handling austenitic, super duplex & nickel based alloys, special care should be taken to avoid contact with other non-corrosion resistant materials such as contaminated metal inspection tables, metal forks, chains, and cables.
H2S corrosion in the presence of tensile stress may result in catastrophic failure as a result of hydrogen embrittlement by mechanisms such as Sulfide Stress Cracking (SSC) and Stress Corrosion Cracking (SCC).
API 5CRA provides detailed testing requirements for satisfaction of the specification. The testing requirements vary by group, or alloy family. This article summarizes the testing requirements for Groups 2, 3 and 4.
