How much pressure to make the punch?

Ralph here is a chart for punching holes in mild steelOriginally Posted by Ralphxyz

It is never recommended to punch a hole smaller in diameter than the thickness of the steel.
However, I used to regularly punch 3/4" holes in 1" plate by heating it above 600°f in an oven prior to punching
Never try to tell me it can't be done
When I have to paint I use KBS products

HI:
The pressure is the circumference x the thickness x the sheer strength of steel, so guessing at the sizes:
(1" dia x Pi = 3.14 ) x 1/2" thick x 30K psi for steel = 24 tons
Iron workers have very generous punch / die clearance which will drop the tonnage required.
