Hadfield austenitic manganese steel in the as-cast condition contains (Fe, Mn) 3 C carbides. It is a common industrial practice to solutionize the material before use so that (Fe, Mn) 3 C goes into solution giving completely austenitic structure. Generally, it is solution-annealed at 1,050 °C for few hours followed by water quenching.
