I've not cut much stainless, only thin stuff.
I vaguely remember from my cut charts that you need a "hotter" torch for stainless vs mild steel.
One commercial guy I knew who cut all day every day had a rule of thumb he had which was 10 amps per mm of steel. So by his benchmark, 45 amps is too low, I'd try 60-80 amps depending on available consumables..

I go by Hypertherm's charts and use the lowest current I can.

Perhaps that's a mistake, but they say 45A will cut 1/4" stainless so I assume that'll give me the best cut vs more current and higher speeds.

I'm certainly open to suggestions tho.

Speaking as a former career welder, higher amperage (temperature) with correct travel speed will yield better results on thicker material than running at the lowest possible amperage, much the same as when welding as the heat input and travel speed principles are essentially the same in most cases. There's also the added benefits of reduced tendency for warping of the material, as well as higher productivity.
