Abstract

Six metal alloys were subjected to surface and creeprupture stress corrosion tests using NaCl- and Q-brines. Low-allou materials do not seem to be suitable as a barrier against salt brine attack due to the high surface corrosion rate. Creep-rupture strength corrosion was insignificant for the tested materials. Hastelloy C 4 showed no corrosion attack by salt brines in autoclaves at 200°C and 100 bar during 8 months of testing. Bentonite was shown to reduce the corrosion attack considerably.
