Hot forming of steel - Force calculations

(OP)
I am looking at the logistics for hot pressing some steel plate for a job and would appreciate any references that i can look up for caculating the forces required. An example of one of the parts is as follows

material- Steel plate ST37 20mm thickness

Profile- Round dish. Central aria flat dia 500mm coneclly dished to dia 1000mm with a depth of 100mm

All help most appreciated

RE: Hot forming of steel - Force calculations

What is ST37 steel?  Can you tell me the composition?

If you are 'bending' the material only with very little plastic forming, the loads will be quite low.  If you are causing large bulk deformation of the material, you can estimate 25-35 tons/in^2 of plan view area on a mechanical press as a rule of thumb for low to medium carbon steel (<.45 Carbon).   Depending on the type of forming, you may cause overheating, buckling, or tensile failure during forming.
