Resumen

This paper analyses the failure of a set of disc springs, broken in service in a seawater environment and at high temperature. These components were manufactured using a 17-7 PH, UNS S17700 precipitation hardening stainless steel. The morphology of the cracks was intergranular and it was attributed to hydrogen embrittlement due to the hydrogen that entered into the steel during the acid pickling. This hypothesis was confirmed by baking the samples to remove this hydrogen. This action increased significantly the ductility of the steel and modified the morphology of the fractures.
