摘要

This contribution reports the impact of retained austenite on the corrosion behavior of plastic molding grades such as Vanax Super Clean, Tyrax ESR, Stavax ESR, Mirrax ESR, and Elmax Super Clean. For each grade, austenitization at two different temperatures was carried out and samples in as-quenched condition were compared with as-quenched condition with deep cryogenic treatment (deep cooling). The corrosion behavior was characterized using cyclic potentiodynamic polarization method in 0.1 M NaCl solution, and the retained austenite content was characterized using XRD. The corrosion behavior response corresponding to retained austenite content was discussed.
