Abstract
The theme of this work is the evaluation of the base material and weld joint of supermartensitic steel exposed to sulphide stress cracking. This type of corrosion stress cracking is tested according to NACE TM 0177. In this study was evaluated Supermartensitic steel 13Cr6Ni2.5Mo by SSC method A. All samples were subjected to failure. The fracture surfaces of these samples were subjected fractographic analysis on a scanning electron microscope.
