I don't know. Stainless is nasty. I would try plasma cutter (I like that it's like the erase tool in GIMP, just for steel), cut-off wheel or the jigsaw with the tungsten carbide you mention. That will be definitely harder than the material. Not sure however how big are your teeth if it cannot somehow jam. And what cutting speed you get.

With stainless you don't have to bother painting the outer surface. The black paint still, but you can leave out the primer.

Did you scavenge it from the standard London street skips?
