Resumo: Slow Strain Rate Tests (SSRT) is a methodology to assess the influence of hydrogen in stress corrosion cracking. However, additional information correlating SSRT and hydrogen permeation might provide a better understanding of the influence of hydrogen on susceptibility to failure of materials. This paper presents a new methodology connecting SSRT with hydrogen permeation tests in the presence of hydrogen. The internal part of an SSRT specimen was used for hydrogen generation, whereas its external surface was used to detect hydrogen permeation during SSRT. The results showed a good correlation between the hydrogen permeation with parameters of SSRT.
