I have a piece of white cast iron:
Composition: 2,5% C and 20% Cr
Hardness: HV 750
Dimensions: 40x40x6 inches
Micro structure: Chromium carbides are dispersed in the material.
How can I cut through 6 inches of this material without heating it above 200-300 =B0C (is spark erosion the only way)? Preferably it has to be economic.
