摘要

U-bent and notched tensile tests in a 80 degrees C salt-spray environment were conducted to evaluate the effect of cold rolling at room temperature (CR), warm rolling at 150 degrees C (WR), and a sensitization at 650 degrees C/10 h (CRS and WRS) on the hydrogen embrittlement (HE) susceptibility of the 304L stainless steel. The CR specimen exhibited the highest crack growth rate with a greater number of short cracks found in the CRS specimen in U-bent tests. The CR specimen was resistant to HE in notched tensile tests relative to other specimens. Cracking in these specimens was more likely to initiate at the slip bands.
