Difference Between Strength and Hardness - Minaprem.com

WebTensile strength is the resistance of steel to breaking under tensile tension. It’s used to specify the point when steel goes from elastic (temporary) to plastic (permanent) deformation. Usually, it’s measured in units of force per cross-sectional area. Once a piece of steel is pulled past its tensile stress point, it will split apart.
