(a) Interpretation: The cooling rate of 4320 steel of hardness HRC35 needs to be stated. Concept Introduction: Material hardness is the property of a metal due to which material resist the plastic reformation. Plastic reformation means material reformation which undergoes non-reversible change. Hardness is the property of any material due to which it resists to bend, scratch or any other deformation. Hardness is not constant or fixed for all material, but it depends upon strength and plasticity of metal, material hardness is expressed in terms of hardness number.
