"An investigation of an influence of metallurgical and technological factors on properties of grade X52 to X70 steel plates used for sour and nonsour service. The plates have to meet severe criteria from the point of view of mechanical properties, resistance against brittle fracture, but also from the point of view of their resistance to hydrogen induced cracking (HIC). The main objective is to obtain required mechanical properties and HIC resistance in complex micro alloyed (Ti-Nb-V) C-Mn plates with reduced carbon and manganese contents for plate thickness up to 20 mm."@en . . . .
