Austenitic Cr-Mn steels with additions of C, N, Ni, Mo, Nb, V, or Si are used for specific and important applications in the power generating industry (1). One of the best known applications is in retaining rings for generator rotors (2,3,4), but a large number of other applications is presently being explored or considered, such as superheaters, heat exchangers, condenser tubes, etc. Austenitic Cr-Mn steels are considered when a high-strength, nonmagnetic material is required. Fe-Cr-Mn alloys can also be made stainless and can have a price advantage over Fe-Cr-Ni stainless steels at a given strength level. Some of the austenitic stainless Fe-Cr-Mn steels are reported to be more resistant to stress corrosion cracking than 304 in the boiling 42% MgCl2 solution (5).
