Beschreibung
Zusammenfassung:	The invention provides a coated stainless steel strip (1) product with a dense and evenly distributed aluminum layer (2) on one side or both sides of said strip. Said layer consists of essentially pure aluminum, the thickness of said layer is maximally 15 µm, the tolerance of said layer is maximally +/- 30 % of the layer thickness, the Cr content of the steel strip substrate is at least 10 %, and that the layer has such a good adhesion so that the coated steel strip can be bent 180° over a radius maximally equal to the thickness (3) of said strip without showing any tendency to flaking or the like. The Al-coated strip product is suitable for applications in environments with high humidity or in wet conditions, such as outdoor life applications, sports and sea-life, household and personal care. L'invention concerne un produit à bande (1) d'acier inoxydable recouvert par une couche (2) d'aluminium dense et répartie uniformément, ladite couche étant disposée sur un côté ou sur les deux côtés de la bande. Ladite couche comprend de l'aluminium sensiblement pur, l'épaisseur maximale de la couche correspond à 15 mu m, sa tolérance maximale correspond à +/- 30 % de l'épaisseur de la couche, le contenu Cr du substrat de la bande en acier inoxydable est d'au moins 10 %, et la couche présente une bonne adhérence, ce qui permet de la courber à 180 DEG , sur un rayon égal à l'épaisseur (3), sans risque d'écaillage ou analogues. Le produit à bande d'acier inoxydable convient pour des applications dans des environnements à haute humidité ou mouillés, telles que des applications d'activités en plein air, des applications pour les sport terrestres ou nautiques, des applications domestiques ou de soins corporels.
