The results of investigations conducted to deter mine the mechanical and metallurgical properties and weldability of the 18-nickel maraging alloy steels. The information in this report relates specifically to the results of studies conducted to 1 establish the mechanical and metallurg ical properties, including fracture toughness, of parent-metal 18-nickel alloy steels processed by different melting techniques 2 determine the effect of varying weld-wire compositions on the mechanical and metallurgical properties of TIG-welded 12-in.-thick material 3 determine the effect of the MIG and submerged-arc process on the mechanical and metallurgical properties of welded 12-in.-thick material and 4 deter mine the fracture toughness of weld deposits and heat-affected zones. The selection of an optimum material was based on the results of these studies. A supplemental program, which has increased the scope of fracture-toughness testing, was authorized. Progress made on this supplemental program is also presented.
