Abstract The effects of hydrogen atted (HA) caused by exposure to hydrogen atmosphere at different temperstures under 18MPa for 240hrs on mechanical Properties for 20G steel were studied. In this study hydrogen attack intensity was defined as % of strength loss. The tensile tests showed that tensile strength decreased considerably with increasing hydrogen attack. The COD testing indicated that δc,KIC decreased with increasing hydrogen attack. The variation of threshold △K value with hydrogen attack was not so simple.It decreased initially and then increased, resulting in a valley on △K～HA % plot. It was suggested thst the knowledge of influence of HA % on △Kth and KIC would be important for engineering practice.
