A holistic approach to diagnose the occurrence of cracking on HSLA steel slabs and propose countermeasures prevent them is presented. The consisted plant monitoring, including direct temperature measurements in strand with pyrometers. Extensive characterization was performed via thermo-mechanical tests microscopy techniques which revealed combination Widmanstätten ferrite, acicular ferrite seco...

The review of non-destructive testing pressure vessel for compressed air is given, as well the assessment and analysis defects on integrity itself. focus here welded joints, most critical areas in vessels, especially if thickness large, like case considered (50 mm), cylindrical storage vessels made HSLA steel. Toward this end conventional NDT methods, such UT Radiography are used first phase re...

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...
