Full Description

Because of difficulties in establishing appropriate criteria for evaluating transition-temperature curves for steels of different strength and thickness, a study was initiated to investigate various energy-absorption, lateral-expansion, and fracture-appearance criteria for five steels having yield strengths in the range of 40 to 140 ksi (tensile strengths of 60 to 150 ksi) and for thicknesses corresponding to quarter-, half-, single-, and double-width Charpy V-notch impact-test specimens. The transition-temperature curves for the five steels (ABS-C, A302-B, HY-80, A517-F, and HY-130) are summarized in this bulletin.
