Stainless Steels in warm, damp and chlorine environments.

Youtube has some great resources on it.

Grade A2 nuts and bolts, by the sea, end up like a Swiss cheese. A4 is what you want.

But not in a warm chlorine environment, still not good enough.

Chlorine can be produced from seawater quite easily with electrolysis.

It is routinely for offshore rig and ships, it uses plastic and titanium components.

What is, making chlorine or preventing it being made?

Making chlorine - rigs make chlorine and add to the cooling water - this is generally seawater. The chlorine is to kill stuff and act as biocide. Otherwise you get mussels etc growing within the heat exchangers.

 

The chlorine makers take seawater, the by products are highly corrosive, the off gas from the process is hydrogen.

 

Generally chlorine making is a very simple, but at the same time a very unreliable process.

I know using stainless electrodes for electrolysis isn't a good idea as it produces toxic hexavalent chromium, Cr6+ at the anode.

 

It does work mind as I've tried it.
