2.4LeebHardnessTestingPrincipleIt is defined as the quotient of an impact body’s rebound velocity over its impactvelocity, multiplied by 1000. Harder materials produce a higher rebound velocitythan softermaterials. For a specific group ofmaterial (e.g. steel, aluminum. etc.).Leebhardnessvaluerepresentsadirectrelationshiptoitshardnessproperties. Forordinary metal, conversion curves of hardness HL versus other standard statichardness (HB, HV, HRC, etc.) are available, enabling you to convert HL into otherhardnessvalues.
