Abstract Cold deformation can effectively enhance the strength of austenitic stainless steels. In this paper, a high nitrogen austenitic stainless steel with 1.0wt.% nitrogen and the 316L stainless steel were investigated on their microstructures, true stress-strain curves and micro-hardness after compressive deformation at room temperature. It was found that both the mechanical twins and the slips participated in the deformation for both two steels under the deformation less than 20%, but the slips turned to be dominant for 316L when the deformation was increased to 50%, the high nitrogen steel still remaining the above two mechanisms. There was no α’ martensite transformation in the high nitrogen steel under deformation, showing better structure stability, but there was martensite in the 316L. The strength, the micro-hardness and the work-hardening effect of the high nitrogen steel were much higher than those of the 316L, and the strength could be largely enhanced by cold deformation for the two steels. The micro-hardness was related to the crystal orientation for the two steels and the effect of crystal orientation was larger than that of the microstructure inhomogeneity. The mechanism of the high nitrogen stainless steel showing excellent properties was also analyzed and discussed.
