On the other hand, the addition of a film-forming corrosion inhibitor based on modified imidazolines eliminates completely the development of cracks, although under certain test conditions, it can favor localized pitting corrosion. In the present work, the susceptibility astm g46 G466 5L X52 steel to corrosion processes was evaluated in the presence of high contents of hydrogen sulfide and carbon dioxide.

The pitting occurred in the astm g46 of chlorides at astm g46 near neutral pH where aluminum would be expected to exhibit good resistance to corrosion.
