I recently bought a new house. Behind the shed on the property is a 55 gallon barrel. It appears to be stainless steel (magnet will not stick to it) with a welded fitting on the side. Very very heavy. The real estate agent mentioned that the old man who previously owned the house may have had some brewing purpose for it in mind but never got around to it.
It's dirty but seems to be structurally sound. There's some slight surface rust/oxidation on the interior but it doesn't look deep at all.
The markings on the bottom of the barrel are as follows...
Pictures are below.
My question is... Does this barrel have a use in a homebrewing set up and if so, what would that be? I'm a simple extract brewer and have never done all-grain or built a rig, so I can guess but couldn't say for sure. Would it be of use? Does the rust out-and-out disqualify it? Does it have value? What do you guys think?
Almost all process equipment is 316 but it will fine for homebrewing
Even stainless steel will surely rust, it's compatible with everything. Hydrochloric acid will burn it right up. Probably your rust is stuff that is on the surface, and that is corroding in the elements.
