Abstract : Studies were made to complete the laboratory phases of an HY-130 weldment development. Final laboratory composition studies showed that the standard 5Ni-Cr-Mo-V steel can meet the mechanical-property requirements for an HY-130 base metal in plates through 6 inches thick. A fourth 80-ton electric-furnace heat of the 5Ni-Cr-Mo-V steel has been produced, and the mechanical properties of plates confirm the predictions indicated by the final laboratory composition studies. The laboratory development of the Air Reduction 2Mn-2Ni-Cr-Mo MIG filler metal is essentially completed. Evaluation of this filler metal indicates that the properties of the weld metal, including those of weld metal deposited out-of-position, meet the requirements for an HY-130 weldment.
