Abstract. The strength differential effect (SDE) (i.e., the tension-compression asymmetry of stress-strain curves), for a ferritic stainless steel sheet was measured using an in-plane compression test. It was found that the in-plane compressive flow stress was 4-7% higher than the uniaxial tensile flow stress in both the rolling and transverse directions. In addition, bending moment-curvature curves were obtained from a pure bending test. These curves were found to be in good agreement with those calculated with SDE taken into account. Thus, the validity of the measured SDE was confirmed by the bending experiment.
