Description

Raw data to evaluate hydrogen-assisted cracking of three tempered martensitic steels (Ref -0.3C0.2Si0.4Mn1.0Cr0.8Mo, HMV-0.3C0.3Si0.3Mn0.5Cr-1.8Mo0.2V, HCV-0.6C0.3Si0.3Mn1.0Cr1.2Mo0.15V). It comprises: -Tensile tests: Unnotched and notched (Kt1.3, 1.5, 2.1, 4.2) round specimens: -> Air (without hydrogen) ->Hydrogen electrochemically pre-charged (20, 50 or 100 mA/cm2) and desorbed (30 minutes or 48 hours) Unnotched and notched (Kt1.1, 1.4, 3.2) flat specimens: -> Air (without hydrogen) ->Under electrochemically hydrogen permeation (5, 20 or 50 mA/cm2) -Electrochemical permeation: Stress free samples (5, 10, 20, 50 and 100 mA/cm2) Tensile loaded samples (5, 20 or 50 mA/cm2)
