Both steels were characterized in the as-rolled state and after being submitted to NACE TM284/87, pH 3.5, test. Microstructure, mechanical properties and fracture behaviour have been determined along with the internal cracking due to hydrogen. The appearence of these cracks were located in reference to the geometry of the plate and the way they propagate through the steel microstructures was aldo assessed. ER -
