Uranus B6 barrel suitable for chlorhydric pickling?
Will URANUS B6 barrels resist to 50% chlorhydric pickling? We already use them for 10% sulfuric pickling; we need to change the bath for a chlorhydric one.
What do you think about it?
Thanks for your answer.
Hi, Guillaume. I'm not familiar with that brand and model, but I've never seen hydrochloric acid present a problem for polypropylene plating barrels, assuming that's what they are. good luck.

Depending on concentration and temperature, hydrochloric acid will be more aggressive to chrome, nickel, some stainless steels and to the steel in your building than sulphuric. If this is a long term and high volume project, I suggest you get professional advise.
Bonjour Guillaume !
I tend to agree with Guillermo's response, HCl will definitely attack the chrome content and Ted seems to hit the barrel on the head, so to speak, when he opted for Polypropylene.
But Guillermo's reply on 'getting professional advice' is, I think, incorrect. HE IS, as is Ted, a PROFESSIONAL, where else could you go for information other than the supplier of Uranus B6 who might well be biased?
