Abstract
A micro-alloyed low carbon steel strip is obtained by hot rolling at temperature of the pre-strip never lower than 900° C. and shows such metallurgical and geometrical features, as well as relating to planarity and deformability, to render the same suitable to obtain structures of low weight and good mechanical resistance, thus being able for use in replacement of cold rolled strips for the production of finished stamped or cut pieces. Said steel strip, having thickness>0.7 mm, has a ratio yield load/breaking load>70%, a fine grain structure better than grade 10 of ASTM E 112 standard in a percentage higher than 90% of the whole structure and a ratio between breaking limit under strain and yield point σ/RPo.2>90%.
