Zinc Coated Cold Rolled Galvanized Steel Strips And Coils Bao Steel HDG GI SECC DX51D

The mechanical properties of electrogalvanized sheet are approximately the same as those for the equivalent grade (steel designation) of cold rolled sheet, because the steel coils are pre-annealed prior to processing on the electroplating line. For example, DDS cold rolled sheet and DDS electrogalvanized sheet have similar mechanical properties. This does not mean that electrogalvanized product will behave similarly during stamping/drawing. The coating influences the behavior during forming; thus, special practices are required when stamping electrogalvanized products. With the correct type of die material, clearances, etc., the stamping performance of the two products are similar.
