The process includes casting directly from liquid metal a steel strip 1.5 to 10 mm in thickness, subjecting the cast steel strip, in the austenitic phase, to a first hot rolling operation in one or more steps at a temperature of between 950° C. and the Ar3 temperature of said strip with an overall reduction ratio of at least 10%, then subjecting the hot rolled strip, in the ferritic phase, to a second hot rolling operation in one or more steps at a temperature below 850° C., with an overall reduction ratio of at least 50% in the presence of a lubricant, so as to obtain a hot-rolled sheet with a thickness of less than or equal to 2 mm, and recrystallizing the hot rolled sheet at a temperature between 700 and 800° C. The composition of the steel strip comprises (in weight %): carbon less than 0.1%, manganese from 0.03 to 2%, silicon from 0 to 0.5%, phosphorus from 0 to 0.1%, boron from 0 to 0.002%, titanium from 0 to 0.15%, balance iron and impurities.

摘要： 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 σFp/RPo.2>90%.
