Abstract

L'invention concerne un acier polyphasé, un procédé de production de produits laminés à partir dudit acier comportant jusqu'à 70 % en volume de structure polygonale-ferritique, ainsi que son utilisation. L'acier doit être très résistant, présenter une bonne aptitude au façonnage à froid et une meilleure qualité de surface après la dernière étape de déformation à chaud.
