Hardness - Wikipedia

Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion.In general, different materials differ in their hardness; for example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin, or wood and common plastics.Macroscopic hardness is generally characterized by strong ...

Difference Between Strength and Hardness

Strength is a basic property of the solid material. Hardness is not a property of solid material; in fact, it is the property of solid surface. Strength of a solid material can be determined by standard tensile or compressive testing in Universal Testing Machine (UTM). Strength is expressed by N/mm 2; by the by, strength is nothing but stress.
