Din 50961 Fe Zn 8b ((free))

DIN 50961 assigns corrosion resistance classes based on the passivation type and thickness. For Fe Zn 8b (yellow passivation):

However, be careful: Some engineers misinterpret this as an "average" thickness. The standard clearly states that for significant surfaces, no individual measurement may fall below 8 µm. din 50961 fe zn 8b

If the part is for export to the EU, add: "Compliant with EU Directive 2011/65/EU (RoHS 2)." DIN 50961 assigns corrosion resistance classes based on

"DIN 50961 Fe/Zn 8/B" is a technical specification for an electroplated zinc coating applied to iron or steel components to provide corrosion protection. This designation specifically defines the base material, the coating metal, its thickness, and the type of chemical post-treatment applied to the surface. Breakdown of the Designation If the part is for export to the

The number "8" represents the thickness of the zinc layer. Specifically, this number corresponds to the "service condition" or thickness class defined in the standard.
