By rapid heat treatments surface layers with properties that are distinctly different from those of the initial microstructure can be generated. In case of high nitrogen steels the rapid heat treatment aims at generating a hard surface with compressive residual stresses and high corrosion resistance. Here, the microstructure, the residual stresses and especially the corrosion behaviour of the rapid heat treated high nitrogen steel X30CrMoN15 1 and the reference steel X39CrMo17 1 are presented in dependence of the maximum heat treatment temperature and the heating rate.
