Abstract : Work was continued to develop a submarine-hull weldment with a yield strength in the range 130 to 150 ksi (HY-130/150). Because previous stud ies indicated that an experimental 5Ni-Cr-Mo-V steel was very promising as an HY-130/150 steel, an 80-ton electric-furnace heat of the steel was produced. No difficulty was encountered during production, and 1/2- through 4-in.-thick plates of the steel exhibited an excellent combination of yield strength (139 to 144 ksi) and notch toughness (80 to 87 ft-lb Charpy V-notch energy absorption at 32 F). Studies on other types of HY-130/150 steels and on the effect of minor elements on the properties of the 5Ni-Cr-Mo-V steel are essentially completed. (Author)
