    摘要： The invention relates to a sheet-metal layer (1) having anti-diffusion structures made of a high-temperature-corrosion-resistant steel, having a longitudinal direction (Q) and a top side (2) and a bottom side (3) and a thickness (d) of 0.015 to 0.1 mm, wherein the sheet-metal layer (1) comprises discontinuous microstructures (4, 5) extending approximately in the longitudinal direction (Q) and having the following characteristics: a. the microstructures (4, 5) have a structure height (SH), a structure length (SL), and a structure width (SB) and among each other a distance (LA) to the nearest microstructure (4,5) aligned approximately in the longitudinal direction thereof, said distance being formed by interruptions (6), and a lateral distance (SA) to the nearest laterally adjacent microstructure (4, 5); b. the microstructures (4, 5) are designed so that some of the microstructures project out of the sheet-metal layer (1) toward the top side (2) and some of the microstructures project out of the sheet-metal layer toward the bottom side (3); c. the microstructures (4, 5) are spaced, arranged, and designed in such a way that each straight theoretical line (G) extending across the sheet-metal layer (1) perpendicularly to the longitudinal direction (Q) intersects with at least two microstructures (4, 5) projecting toward the top side (2) and two microstructures projecting toward the bottom side (3); wherein d. the following relations apply: the structure height (SH) is 0.02 to 0.1 mm, preferably 0.06 to 0.08 mm, the structure length (SL) is 2 to 10 mm, preferably 4 to 6 mm, the structure width (SB) is 0.2 to 1 mm, preferably approximately 0.5 mm, the longitudinal distance (LA) to the nearest microstructure aligned approximately in the longitudinal direction thereof is greater than 2 mm, preferably 4 to 8 mm, the lateral distance (SA) to the nearest laterally adjacent microstructure (4, 5) is 1 to 10 mm, preferably 2 to 6 mm.
