摘要
The steel having improved deep-drawing properties is characterized in that it contains carbon in a proportion of less than 0. 015%, manganese in a proportion of from 0.15 to 0.25%, sulfur in a proportion of less than 0. 012% and aluminum in a proportion of less than 0.04%.PP This steel is intended for the production of thin sheet metal intended for deep-drawing, in accordance with a process comprising, in particular, the following operations:PP production, in a converter, of a steel having the above composition; PPhot-rolling entirely in the austenitic region;P Pwinding at a temperature higher than 650° C.;PP continuous annealing, after cold-rolling, at a temperature below 700° C.
