What Is Hardness? Hardness measures the resistance to localized plastic deformation caused by force or abrasion. Materials with high hardness would generally be stronger and more wear-resistant but, on the other hand, more brittle and sensitive to fracture. Hardness is a broad topic that is well covered. In this post, we will cover it from the machining perspective.
