: The German technical standard (Deutsches Institut für Normung) governing electroplated zinc coatings on iron or steel. Note that this has largely been superseded by ISO 2081 in modern manufacturing. Fe : Represents the base material, which is iron or steel . The coating system is designed for steel substrates
: After the zinc layer is set, the part receives a "b" treatment—a chromate conversion coating
