The effects of an 8 T magnetic field on the 0.2% flow stress and serration of 304L and 316LN steels were examined using a clip-on gage after calibrating the outputs of this gage and the load-cell both in 0 and 8 T magnetic fields. In 304L steel the effects of the magnetic field on Young’s modulus, 0.2% proof stress and ultimate tensile strength were small, whereas a small decrease in elongation was observed to occur in an 8 T magnetic field. As for 316LN steel, it could be seen that 0.2% proof stress was decreased by the application of an 8 T magnetic field, but the amount of the decrease was very small and was not significant. Young’s modulus had considerable scatter and the effect of an 8 T magnetic field on Young’s modulus was not clear. The effects of an 8 T magnetic field on work-hardening behavior were negligibly small in 316LN steel, but the work-hardening after about 10% strain was increased by the magnetic field application in 304L steel. Effects of the magnetic field on the onset strain of serration were not determined in 304L steel, but in 316LN steel the initiation of the serration was observed to be delayed by the application of an 8 T magnetic field.
