DX51D hot-dip galvanized steel
The hot-dip galvanized steel DX51D in accordance with the 10346 standard is an essential material in modern metal processing. This high-quality steel, which is listed under the material number 1.0917 (formerly 1.0226), is characterized by its excellent cold forming properties and is one of the soft steels that have been specially developed for demanding forming processes. The classification as machine-seam quality also underlines its particular suitability for automated production processes, where precision and consistent quality are of central importance.
The hot-dip galvanizing process, in which the steel is passed through a bath of molten zinc, results in a uniform zinc coating that protects the steel from rust and other environmental influences. The galvanizing process according to DIN EN 10346 ensures that the coating has high adhesion strength and resistance. The standard specifies requirements for the chemical composition, mechanical properties, and coating thickness of the zinc layer to ensure consistent quality.
