Abstract

P92 heat-resistant steel has been successfully submerged arc welded by employing designed CaF₂–Cr₂O₃ fluxes. It has been demonstrated that δ-ferrite is retained in the weld metal, the area fraction of which is found an approximately 3.7-fold enhancement as the Cr₂O₃ content in the fluxes is raised from 5 to 25 wt pct. Such phenomenon has been elucidated through governing element transfer behaviors incurred by the decomposition of Cr₂O₃. Our findings possibly offer a viable solution towards developing welding fluxes geared towards durable heat-resistant steel grades.
