Evaluation Of Corrosion Resistance Of A Duplex Stainless Steel "Ferralium" In Dead Sea Brine
MetadataShow full item record
Corrosion behavior of Ferralium Alloy 255 during service in the environment of concentrated Dead Sea brine has been investigated. It was found that, the corrosion attack is intergranular and exists only in the weld heat effected zone (HAZ). It starts at ferrite/austenite grain boundaries and in the ferrite matrix, where chromium nitride precipitates and then propagates with acceleration in the rest of the metal due to the abrasive action of the slurry.
