METHOD FOR THE HEAT TREATMENT OF STEEL STRIP ROLLED COLD METHOD OF STRIP STEEL ADAPTED CHEESE AND STEEL STRIP OBTAINED.

摘要

The present invention relates to a method for heat treatment of a cold rolled steel strip comprising a heating to a temperature above the annealing suspérieure annealing temperature to the temperature A3 and stabilizing thereto, cooling to a temperature in the intercritical area between A1 and A3, a stabilization thereto and a martensitic quenching. The invention also relates to a method for manufacturing a steel strip adapted to the cheese, in particular deep drawing, using said thermal processing method and a steel strip suitable for forming obtained by said method.
