Challenger keg ‘challenge’

[IslandLizard]

Thanks for the clarification. These are the physical realities I needed to know about. If it’s impossible to repair then so be it.

Before chucking the keg, perhaps put a grinder or a sharp file on that area where you want to solder and try it again. Nothing to lose, project keg.
I do wonder if there are specific solders and fluxes for these applications.
@Bobby_M may know.

If no go, dismantle it, all the parts are surely worth keeping.

There was someone on HBT looking for keg rubbers in the last few days...

Cheers!

If it were just one pinhole, I'd agree with that but 4 indicates a much wider degradation. The soldering itself will involve at least the heat of a butane torch multiple times... Stainless Steel ceases to be 'Stainless' under a sliding scale of heat/time, and to do that to metal that has already shown it's affliction with 'Steel-Cancer'....well, it just won't last long and as one who has issues with ingesting nickle and chromium in the molecular form that does the body no good.....well; I won't even use PC shanks or taps for the same reason.
The first thing I taught as a kid about working with steel, and then learned for myself both theoretically and empirically in the many years since: Oxidation is Steel-Cancer. To properly repair it, you must cut away and replace all the oxidized portion... Stainless brings with it another set of rules involving the manner in which it oxidizes. It's desirable mostly non-reactivity and non-corroding is the result of intentional oxidation on the surface through passivating.. The oxidation is kept to the outer surface. Once that surface has been comprimised though, a chain-reaction has begun below the surface that must be cut away to fix and with the size of the area involved, it'll require enough heat applied to begin an uncontrolled oxidation throughout unless it is properly polished and passivated.
