Does anyone who has previously worked on MSC Marc worked with the concept of element activation and deactivation...?

I need to do a simulation wherein a hole is required to be punched in an alloy steel bar.

The issue is that I am not sure as to how to go about this.

If there is anyone who can guide me through this ..I would appreciate it..!!

Krunal. 

Hie,
1] I am Krunal, currently pursuing my masters for University of Sheffield, wherein for my thesis I require to simulate the forging process for commercial vehicle Anti-roll bars using MSC MARC software. 2] I require the flow stress curves for the material 51CrMoV4 at varying temperatures ( approx 850 - 1400 deg celcius ) and varying strain rates ( approx 0.01 to 50 per second). However I am unable to find it....!!
