The relationship between SSCC/HE susceptibility of steel UNS G10180 and UNS G11190 and I-H was determined by the measurement of the stable hydrogen permeation rate (I-H) and the study of SSCC/HE susceptibility of the above two steels in TM-01-77 solution. Environmental sensitive cracking (ESC) of UNS G10180 and UNS G11190 steels can be inspected, evaluated, judged by the combination with the microcomputer system (MCS)/periphery attachment and the designed software.
