Abstract:

Work was continued to develop a submarine-hull weldment with a yield strength in the range 130 to 150 ksi HY-130150. Because previous stud ies indicated that an experimental 5Ni-Cr-Mo-V steel was very promising as an HY-130150 steel, an 80-ton electric-furnace heat of the steel was produced. No difficulty was encountered during production, and 12- 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-130150 steels and on the effect of minor elements on the properties of the 5Ni-Cr-Mo-V steel are essentially completed. Author
