摘要：2?Cr-1Mo-?V steel is used for manufacturing and producing hydrogenation reactors. The coarse-grained heat affected zone (CGHAZ) of welded joints using 2?Cr-1Mo-?V steel have a higher reheat cracking susceptibility than the conventional 2?Cr-1Mo steel. But there is no simple and effective method evaluating reheat cracking susceptibility of CGHAZ in 2?Cr-1Mo-?V steel welded joints at present. Based on Weld C-Ring Test and Gleeble? Thermo-Mechanical Test, a new Notched C-Ring Test to evaluate reheat cracking susceptibility of CGHAZ in 2?Cr-1Mo-?V steel was studied in this paper. According to the fitting relationship between RoA and critical stress, a criteria was proposed preliminarily to determine the reheat cracking susceptibility of 2?Cr-1Mo-?V steel CGHAZ using "not susceptible" and "slightly susceptible".
