DEVELOPMENT OF AN HY-130/150 WELDMENT

Abstract

Basemetal studies were concentrated on mill practices for producing the 5Ni-Cr-Mo-V steel, on final composition-adjustment studies, and on an evaluation of forgings and castings produced from the 5Ni-Cr-Mo-V steel. Significant improvements in the strength and toughness of experimental MIG filler metals were observed in recent studies. However, many additional experimental MIG and covered-electrode filler metals are still being evaluated. Initial low-cycle-fatigue and corrosion studies comparing the 5Ni-Cr-Mo-V steel with HY-80 steel were extremely encouraging. Plates of the 5Ni-Cr-Mo-V steel up to 3-3/8 inches thick were cold-formed in a shipyard and the results of the study showed that the 5Ni-CrMo-V steel readily meets the forming requirements.
