Weldability of Cr-Mo steels for fossil energy applications
Technical Report
·
OSTI ID:5276540
This research program was undertaken to provide fundamental and basic metallurgical information on the behavior of the heat-affect zone (HAZ) in Cr-Mo steel welds, as well as practical information on their relative weldability. The principal work was the evaluation of the stress-relief cracking (SRC) and hydrogen-assisted cracking (HAC) susceptibility of Cr-Mo steels ranging in Cr content from 2 1/4% to 12%. Differences in observed cracking behavior were contrasted with differences in composition, on-cooling transformation behavior and weld microstructure. 86 refs., 106 figs., 12 tabs.
