Paper presented at the CORROSION 2021, April 19–30, 2021
Paper Number: NACE-2021-16447
... Abstract Double-Loop Electrochemical Potentiodynamic Reactivation (DLEPR) is a useful technique to measure the degree of sensitization (DoS) in austenitic stainless steels, as it is fast, nondestructive, and accurate in identifying low to medium DoS. While its use has been well-established...

... of some alloys. Carbides are known to be resistant to attack by molten fluorides and could potentially be used to form a diffusion barrier on alloy surfaces. Alloy S31603 and alumina forming austenitic stainless steel OC5 were pre-oxidized in air or steam atmosphere to form surface oxide film. Chromium...

... steels under tensile loads. Although LME of austenitic stainless steel is more likely when Zn is in its molten state, occurrences of Zn induced LME have been reported at temperatures below 400°C (752°F). Industry has adopted a number of practices to prevent LME of SS pressure-retaining equipment...
