Choose from our selection of grade 1018 steel, including low-carbon steel sheets and bars, low-carbon steel rods and discs, and more. Endurance strength is defined as the maximum value of completely reversed bending stress that a material can withstand for a finite number of cycles without a fatigue failure.

ASTM does not define endurance limit, the stress value below which the material will withstand many load cycles,[1] but implies that it is similar to fatigue limit. [13] However, recent research suggests that endurance limits do not exist for metallic materials, that if enough stress cycles are performed, even the smallest stress will eventually produce fatigue failure.

Maximum typical values for irons are 170 MPa (24 ksi), aluminums 130 MPa (19 ksi), and coppers 97 MPa (14 ksi). Cleveland, Ohio 44128 U.S.A. To learn more, please refer to the cookie policy. Sign up for our eNewsletter now to stay in-the-know. Typical case hardened to a range Rockwell “C” 60/65.
