The American Society for Testing and Materials (ASTM) has published the standard "Electrolytic Chromium Coated Black Plate, Single and Double Reduced" under the designation ASTM A657/A657M-18(2024). This standard provides guidelines for the manufacturing of black plate with an electrolytic chromium coating. It outlines specific requirements concerning single-reduced and double-reduced products in terms of chemical composition, mechanical properties, dimensional tolerances, surface finish, and testing procedures.
The document specifies that the chromium plating process must meet certain thickness standards to ensure durability and resistance against corrosion and wear. Additionally, it includes provisions for quality control through visual inspection, measurement techniques, and chemical analysis to verify compliance with the stated specifications. The standard also addresses environmental considerations and safety practices related to the production of these materials.
This ASTM A657/A657M-18(2024) revision updates previous versions by incorporating advancements in technology and industry needs, ensuring that manufacturers have access to up-to-date guidelines for producing high-quality electrolytic chromium coated black plate suitable for various applications including automotive parts, electrical components, and household appliances.
