I am designing a down hole punch tool.
It is required to punch through0.430" thick (OD 5.555) casing made of Super 13 Chrome 110ksi material. The punch button is 0.675" diameter.
So far the tungsten carbide buttons crack and teh last one disintergarted and wiped out the test fixture.
The compression load through the button to shear is 110,000 lbs and teh compression rating is of the order 240,000 psi.
I want to use a tool steel button heated and temprered, and to cover all basis I'm considering, D3, D6, S1, 440B and CPM M4. I struggling to determine which is the best to use of any of these grades as I only seem able to get basic data or rudimentary wear vs toughness characteristics. The button will only ever be used once and tehn replaced.
I've tried Crucible, Matweb, Globalspec for material data.
What I would like is material properties like tension, tensile yield or better still compression data for heat treated materials of D3, D6, S1 etc. Is these anything out there? I'm struggling to make a decision as to which material to go for. Can anyone point me to the data sheets I need?
Thanks
