Hardness refers to the ability of a material to resist local deformation, especially plastic deformation, indentation or scratches. It is a measure of the hardness of the material. The comparison table of Vickers hardness, Brinell hardness, and Rockwell hardness is shared with you. Collect it now! Commonly used HV=HB=HRC hardness comparison table

There is a wide variety of steel materials used in machining. The range of Machinability is vast and spans from about 40% for difficult to machine steels, such as bearing steel ( SAE 52100 / DIN 100Cr6) up to Ledloy free-cutting steel (SAE 12L14 / DIN 9SMnPb36) that has a machinability rate of about 170%. The Machinability is mainly affected by

The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material. For practical reasons conversion tables are used to convert between one scale and another. References: Materials Science: U.S. Department of Energy

Hardness is the measure of a material's resistance to localised permanent deformation. Permanent deformation is also called plastic deformation. While elastic deformation means that a material changes its shape only during the application of force, a resulting plastic deformation means that the material will not return to its original shape.
