Single cold-reduced electrolytic chromium/chromium oxide-coated steel; part 1: sheets

This technical specification defines the requirements for cold-rolled steel sheets intended for subsequent electroplating with chromium or chromium oxide. It establishes the necessary mechanical properties, dimensional tolerances, and surface quality criteria to ensure compatibility with electroplating processes. The document focuses specifically on flat products, outlining the standards for thickness, width, and flatness that facilitate uniform coating application. It addresses the metallurgical characteristics required for the substrate to support a consistent chromium or chromium oxide layer. The guidelines cover the evaluation of surface defects and the specifications for packaging to prevent damage during handling and transportation prior to the plating stage. By setting these parameters, the document serves as a reference for manufacturers and users to ensure the material meets the prerequisites for successful electrochemical surface treatment. The text details the testing methods and acceptance criteria for the steel sheets, ensuring consistency across production batches and enabling reliable performance in downstream applications where corrosion resistance and aesthetic finish are critical.
