"The aim of the study was to evaluate and quantify effects of plastic strain on subsequent experiments of hydrogen induced cracking (HIC). HIC tests were performed according to NACE TM 284-87 Standard. Total of 27 specimens was tested and evaluated. Specimens were taken from rolled sheets of X60, X65 and X70 steels to be used for manufacture of spiral welded pipes, nine specimens from each of the steel. Three specimens of each group were loaded to 1% plastic strain, next three to 0.5% plastic strain. The last group was not preloaded. Significant effect of plastic strain on reducing of resistance to HIC was determined particularly for X70 steel and also for X60 steel." . .
