Does anybody have any ideas how I can burn this material quickly on a CNC EDM machine with a copper electrode. The Chemical composition of the material is as follows:
Element Weight %
Carbon .04 Max.
Manganese 1.5 Max.
Phosphorus .04 Max.
Sulfur .03 Max.
Silicon 1.0 Max.
Nickel 4.5 - 6.5
Chromium 24.0 - 27.0
Molybdenum 2.9 - 3.9
Copper 1.5 - 2.5
Nitrogen 0.1 - 0.25
Iron Balance

I would like to try any reasonable suggestions. Thank you.
