The effects of alloying elements on structures, mechanical properties and deformation-induced martensite transformation were investigated in five types of Cr-Mn-Ni austenitic stainless steels: 14%Cr-1%Ni-10%Mn-0.13%N, 15%Cr-4%Ni-8%Mn-0.05%N, 15%Cr-4%Ni-8%Mn-0.12%N, 17%Cr-5%Ni-4%Mn-0.10%N and 17%Cr-6.5%Ni-4%Mn-0.05%N. The relationships between the compositions and their properties were discussed.<br>The constitutional diagram using Cr and Ni equivalents as Schaeffler's diagram did not correspond to the observed structures of cold rolled and annealed sheets in Cr-Mn-Ni stainless steels. The constitutional diagram of Cr-Mn-Ni stainless steels was described using the equations for the calculated ferrite content and the Ms temperature.<br>The effects of alloying elements on 0.2% proof stress in Cr-Mn-Ni stainless steels was almost equal to that in Cr-Ni stainless steels.<br>The effect of Mn on austenite stability, which reveals the ease of deformation-induced martensite transformation, in Cr-Mn-Ni stainless steels was larger than that in Cr-Ni stainless steels. Therefore, the new Ni equivalent which exhibits austenite stability was attained by regression analysis between deformation-induced martensite transformation contents and compositions. A high correlation between this Ni equivalent and the formability of Cr-Mn-Ni stainless steels was recognized.
