Din 50961 Fe Zn 8b (99% Proven)

The part is submerged in a zinc plating bath (acidic or alkaline). An electric current deposits zinc ions onto the negative cathode (the workpiece). The process runs until a minimum local thickness of is achieved.

This specification is very common for:

If you are updating an old technical drawing from DIN 50961 to a modern, environmentally compliant standard, the translation looks like this: DIN 50961 Fe/Zn 8/B din 50961 fe zn 8b
