Maximize Hard Milling with Balanced Machining Process

The measured hardness of typical hardened steels is in the range of 48-65 HRC. However, when it comes to real-world machinability, the Rockwell number does not represent the whole story. For example, D2 tool steel hardens to about 60-62 HRC, but it machines more like 62-65 HRC due to a chromium content of 11-13 percent that increases toughness.

Rock properties OoCities

In carving and lapidary working of rock, rock hardness plays an important role in determining the rocks susceptibility to brittle failure during the working process. Rocks that have high hardnesses are less susceptible to fracturing, and their mineral grains are more tightly held and less likely to be plucked out of the rock's surface while being worked.
