Abstract

L'invention concerne un produit en acier caractérisé en ce qu'il a une composition chimique se situant dans une plage spécifique et correspondant à une formule spécifique établie en fonction de l'environnement d'utilisation dudit produit. Le produit est un produit en acier présentant une excellente résistance à la corrosion atmosphérique, réduite en cas de flux de rouille, et qui forme une rouille stable ayant de bonnes propriétés de protection même dans un environnement à forte teneur atmosphérique en sel, notamment dans les régions côtières. L'invention concerne également un autre produit en acier caractérisé en ce qu'il comporte une quantité totale spécifique d'inclusions de type A et d'inclusions de type B, conformément à la norme JIS G 0555. Ce produit en acier, y compris la partie affectée par la chaleur du soudage, présente une excellente résistance à la corrosion atmosphérique et constitue une excellente protection contre les vibrations.
