The suffix 'b' once allowed yellow (Cr+6) or blue (Cr+3) chromate. Hexavalent chromium (Cr+6) is now restricted under EU RoHS and ELV directives. Consequently, new Fe/Zn 8b coatings use trivalent chromium (Cr+3) passivation, which matches or exceeds the corrosion performance of earlier Cr+6 types. If you need a one-line product label or
