Monotonic-tens ion and low-cycle strain-controlled fatigue tests were performed on longitudinal specimens from three sheets of drawing-quality special-killed (DQSK) steel. The results showed that DQSK steel exhibits a tendency to cyclically soften. When straight lines were fitted to the data for each of the four relationships, the slopes and intercepts of the lines were not different for the sheets investigated.When the results for DOSK steel were compared with previously reported results for USS EX-TEN F50 and USS Dual Phase 80 steels, the total-strain amplitude-reversal data showed little difference among the three grades. However, as expected, the elastic-strain-reversal data and the stress-reversal data were ranked in order of the tensile strength and the plastic-strain-reversal data were ranked in order of monotonic elongation, especially at the longer lives.
