.75 % C content steel
.75 % C content steel
(OP)
We make hydraulic press machines. We are making a cylinder having a diameter of 1100 mm. The piston size is 800 mm. Length of stroke is 150 mm. The maximum pressure we want to exert is 300 kg/cm2. The chemical composition of the steel which we getting is:
C: .75% Cr: 1.3% Ni: .32% Mo: .18%
Will this material be safe since the carbon content if relatively high? Is there any risk in using it as a high pressure cylinder? Will the material be machinable and easily drill-able?
Please help...

Your chem looks sort of like a 6200/6300 grade, but not really.
What spec are you buying this material to?
What is the heat treatment? Properties?
And what wall thickness?
4300psi isn't too high, but at 1.1m diameter you are looking at +3" walls
I agree, not 0.75% C, that is risky.
