The final and often decisive step in this sequence is typically a longer-term test focusing on the performance of corrosion inhibitor candidates against localized corrosion. Despite its fundamental importance in the decision-making process...

.... Abstract Austenitic stainless steels for non-magnetic drill collars (NMDC) may be susceptible to precipitation of Cr-rich phases at grain-boundaries during the necessary thermo-mechanical processing. This condition, known as sensitization, is detrimental to resistance to localized corrosion, stress...
