Abstract To provide a guidance to the industrial production of the austenitic stainless steel sheets, the changing of the cold rolled hardness with the cold rolling reduction of the 304 austenitic stainless steel sheets was investigated. The effect of different thickness reductions by cold rolling on the microstructure and mechanical properties of 304 stainless steels were investigated. The annealed stainless steel sheets were subjected to the cold rolling at room temperature from 10% to 52% thickness reduction. The results indicate that strain-induced martensite transformation clearly results in a significant strengthening of the steel. The hardness and strength of the 304 austenitic stainless steels are improved distinctly. After 40% cold rolling, the Vickers hardness is 2.2 times higher than that of the primary one, the yielding strength and tensile strength are greatly increased to about 880MPa and 1312MPa, respectively, which are nearly 4.2 times and 1.8 times higher than those of the primary one.
