Abstract
A hot rolled low carbon steel strip with a reduced content of silicon and thickness comprised between 0.65 and 1.5 mm can be used in a particularly advantageous way for the production of multilayer packs of cold cut lamination and all those products composed of a number of overlying steel sheets which are required to have a substantial parallelism, planarity and no burrs, providing a valid alternative solution to the cold rolled, non-oriented grain silicon steel strip which is usually employed to this purpose. Said steel strip is characterized by a silicon content < 0.03 %, a thickness preferably between about 0.65 and 1 mm, reduced tolerances of ± 0.05 mm, a parallelism rate < 0.02 mm and a fine and uniform grain structure with the 70% of the ferritic grains comprised between the grades 9 and 12 of the ASTM E 112 standard.
