Chrome Plating Steel: Safe Reuse of Copper Tank?

Summary for chrome plating steel Discussion

Chrome plating steel in a bath normally used for copper rolls is the focus keyphrase here, and the main question is whether MS or SS rollers can be chrome plated in the same tank and what the risk might be. Kaushik Magiawala asked if there would be any problem using a copper-plating tank for chrome plating. In reply, the answerer said he did not anticipate any problem, but cautioned that the exact chrome chemistry matters. He asked Kaushik to specify whether the process uses a Sergeant bath (sulphate catalyst only), a fluoride system, a mixed-catalyst bath such as SRHS, or an MSA-based system such as HEEF-25, because each has different do’s and don’ts. The practical takeaway is that the tank reuse itself does not appear to be a major issue, but compatibility depends on the specific chrome plating solution and process details.
