Excavator Jack Hammer Chisel material

[tarekzad]

Dear Engineers and Expert

We are doing 1.5 Million M3 of Rock Cutting in a Rosy granite rock at a high altitude (2400 meters), we have a high consumption of Chisels since it looks like we are using 40 or 42 CRMO or even less, obviously, these materials can be good for soft and mid hardness rock but not for cutting red and rosy granite rock.

I appreciate your technical support for the most suitable alloy to be used and commercially available.

Thanks for your usual support fellows
