Evaluation of corrosion behaviour on Mn-Cr austenitic steels using 0.1 M HCl solution

One of the attractive low activation steels is the austenitic Mn-Cr steel from the view point of waste disposal because of few long-lived nuclides. In this paper, three types of Mn-Cr austenitic steels were fabricated by vacuum induction furnace. Then plates with 10 mm thickness were fabricated by hot-rolling. The physical metallurgy of these steels was studied by the corrected Schaeffler diagr...
