Beschreibung
Zusammenfassung:	The invention is about high strength steel with a tensile strength higher than 440MPa, which is cold rolled and galvanneal (Fe-Zn alloy) coated by annealing in the continuous galvanizing line, and its feature is; by weight; 0.03 ≤ C ≤ 0.14%, 0.90 ≤ Mn ≤ 1.70%, 0.05 ≤ Si < 0.3%, 0.005 ≤ Al ≤ 0.08%, P ≤ 0.02%, Ti ≤ 0.03%, N < 0.01%, the remainder contains iron and residual elements. L'invention concerne un acier à haute résistance ayant une résistance à la traction supérieure à 440 MPa, qui est laminé à froid et revêtu de galvanneal (alliage Fe-Zn) par recuit dans la ligne de galvanisation en continu, et sa caractéristique est, en poids ; 0,03 ≤ C ≤ 0,14 %, 0,90 ≤ Mn ≤ 1,70 %, 0,05 ≤ Si < 0,3 %, 0,005 ≤ Al ≤ 0,08 %, P ≤ 0,02 %, Ti ≤ 0,03 %, N < 0,01 %, le reste contient du fer et des éléments résiduels.
