Definitions
- the magnesium content of the products according to the invention is between 0.2 and 0.5% by weight and preferably between 0.25 and 0.45% by weight and preferably between 0.25 and 0.35% by weight. in weight.
- a minimum magnesium content of 0.25% by weight is advantageous.
- a maximum magnesium content of 0.45% by weight and preferably 0.40% by weight and preferably 0.35% by weight or even 0.30% by weight is advantageous.
- the unavoidable impurities are maintained at a content of less than or equal to 0.05% by weight each and 0.15% by weight in total.
- the elaborated liquid metal bath is cast in a form of rolling plate.
- the rolling plate After homogenization, the rolling plate is generally cooled to room temperature before being preheated to be hot deformed. Preheating aims to achieve a hot rolling entry temperature of between 400 and 445 ° C and preferably between 420 ° C and 440 ° C for deformation by hot rolling.
- the sheet thus obtained is then dissolved between 450 and 515 ° C.
- the dissolution time is advantageously between 5 min to 8 h.
- the sheet thus dissolved is then quenched.
