Beschreibung
Zusammenfassung:	The present invention relates to a coated steel strip product with a dense and hard abrasion resistant coating on one side or both sides of said strip. The thickness of said coating is in total maximally 25 mum, the hardness of said coating is at least 600 HV and the tensile strength of the steel strip substrate is at least 1200 MPa. The coating is preferably applied by electron beam evaporation and the coating may be, e.g., of A1203. The coated metal strip is useful for the manufacturing of doctor and coater blades for paper and printing industry.
