I think I might have already mentioned it but I'm really interested in using steel in a place which has a history of storing mountains of salt.
In the first week I grabbed a piece of what I thought was steel sheet from the scrap box, covered it in salt, dripped water on it and left it to see what happens. I subsequently found out it was zinc so I just forgot about it.
Then I found it again...
Anyone able to give me the chemical formula of what's going on here?
