摘要：21/4Cr-1Mo-1/4V steel is used for manufacturing and producing hydrogenation reactors. The coarse-grained heat affected zone (CGHAZ) of welded joints using 21/4Cr-lMo-1/4V steel have a higher reheat cracking susceptibility than the conventional 2'/4Cr-lMo steel. But there is no simple and effective method evaluating reheat cracking susceptibility of CGHAZ in 21/4Cr-lMo-1/4V 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 21/4Cr-lMo-1/4V 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 21/4Cr-1Mo-1/4V steel CGHAZ using "not susceptible" and "slightly susceptible".
