AISI 316L stainless steel has been injection molded for the fabrication of small parts of complex geometry. This work consists in pioneer effort to evaluate the high temperature corrosion rate of such material. To that end, corrosion tests have been carried out for 200 h at different temperatures (700°C and 900°C). The nature of the corrosion products was analyzed by optical and scanning electron microscopy, X‐ray diffraction, and EDS microprobe analysis. The results indicated that porosity not only increased the kinetics of the corrosion process, but also determined the nature of the resulting oxide layer.
