WEAR AND TOUGHNESS CHART

General Info The main failure mechanisms of tools are deformation, breakage, and wear. The primary performance properties of tool steels for addressing these failure mechanisms are hardness (resists deformation), toughness (resists breakage or chipping), and wear resistance (resists abrasion or wear). This chart shows the relationship between wear resistance and toughness for tool steels. In most cases, steels are selected for a given application depending on the primary performance issues or failure modes (tool deformation, breakage, or wear). For a discussion of toughness issues and tool steels for breakage or chipping problems, go here. For a discussion of wear resistance and tool steels for longer wear life, go here.
