Abstract

Narrow strips made of steel of high carbon content of between 0.30 and 1 %, which have good suitability for cold rolling. These strips originate from a splitting of a wide strip obtained by hot rolling a slab or ingot on a continuous line while hot, pickling the wide strip rolled when hot, and continuous cold rolling followed by a globulisation annealing. The invention also relates to a process for the manufacture of strips of this type.
