tensile strength. This relationship holds up to a hardness of approximately 40 HRC (~1200 MPa, or 180 ksi tensile strength), and then the scatter becomes too great to be reliable (Fig. 14.5). This does not necessarily mean it is wise to use as high a strength steel as possible to maximize fatigue life because, as the tensile strength increases Introduction to Tensile Testing - ASM InternationalIntroduction to Tensile Testing / 5 Fig. 6 The low-strain region of the stress-strain curve for a ductile material tic contribution and e e is the elastic contribution (and still related to the stress by Eq 3).
