Specifically 1/4" plate.

Hi Curtis,
I believe the inside of our shot blast cabinet is lined with manganese plate (or some variation of it). We had the service guy in here to patch some holes and he used our Oxy/Mapp to cut pieces to go inside. I have to admit the cuts looked pretty rough. I didn't actually see him cutting it, I only saw the plate after it was cut. As far as pressures, I'm not sure.

Thanks John,
Thats what I'm finding, it will cut but it's rough. I've experimented with different flames and have found that a low temperature oxidizing flame works the best. Again I'm just experimenting. Just wondering if I'm missing the obvious or if its even recommended to thermal cut.

Curtis,
I wonder how plasma would handle the cut? Sure does do a nicer job on mild steel.

John,
You're right, plasma does do a lot better, unfortunately the student that was inquiring about this doesn't have access to a reliable plasma cutter. He works on the railroad and much of it is on the cars away from his shop so it's easier for him to use oxy-fuel. Thanks for the suggestion.
