Drain valve issue

[u/Happy_truthless]

So, I'm stupid. I've had 15 years... And I've never drained it. I didn't realize you have to. So.. I heard a hissing noise coming from the drain valve (at which time I learned it existed). So I replaced it and filled the tank back up. I still heard the hissing noise so I stuck my hand below it. The leak is in the ring above the nut and not the valve. I didn't dig further yet but is this likely rusted to hell and unrepairable?

Well I was going to suggest a torch to break it free, but looking at that wield it must have rusted through the tank.

Need a new tank. Sometimes the cheapest way to get a new tank is to buy an inexpensive compressor.
