The purpose of this report is to review in the light of currently existing data the fracture-toughness guidelines for welded ship hull steels first proposed in 1974. The essence of the guidelines was an NDT temperature requirement of 0 deg F for steel used in primary load-carrying members and an NDT temperature requirement of 20 de. F for steels used in secondary load carrying members. A subsidary requirement for primary members was a dynamic tear energy in 5/8 in. specimens, depending on steel strength of 250 to 500 ft-lb. at 75 deg F. Crack-arrest materials would be required to have a dynamic tear energy in 5/8 in. specimens, again depending on steel strength, of 600 to 800 ft-lb. at 32 deg F.
