Metal Substrate Provided With Surface Texture And Method For Applying Such Textures On Metal Substrates
Patent No. EP4003621 (titled "Metal Substrate Provided With Surface Texture And Method For Applying Such Textures On Metal Substrates") was filed by Tata Steel Nederland Technology on Jul 23, 2020. The application was issued on Dec 4, 2024.
Patent Summary
A metal substrate with improved press performance and paint appearance, featuring a surface texture comprising a plurality of depressions with specific dimensions and spatial arrangement. The depressions have a diameter of 25-120 µm, a depth of 0.1-10 µm, and a density of 10^4-10^6 mm^-2. The depressions are arranged such that the arithmetic mean radius of the circle formed by connecting the centers of three closest neighboring depressions is at most 20 µm, and the material area fraction is at least 30%. The substrate is produced by temper rolling and texturing the metal substrate using a texturing means.
