Obtaining high levels of mechanical properties in steels is directly linked to the use special forming processes and addition alloying elements during their manufacture. This work presents a study hot-rolled steel strip produced achieve yield strength above 600 MPa, using niobium microalloyed HSLA with non-stoichiometric titanium (titanium/nitrogen ratio 3.42), rolled on Steckel mill. A major c...

One of the most critical problems related to welding is occurrence Hydrogen-Induced Cracking (HIC), and despite all efforts made mitigate this defect, it remains present in modern industry. Although Gapped Bead-on-Plate (G-BOP) test one practical methods for assessing susceptibility HIC, use a thick plate as base metal (BM) restricts its application. Considering that many materials, such High-S...
