STATIC AND DYNAMIC FRACTURE TOUGHNESS OF 9 PERCENT NI-STEEL AT MINUS 196 CENTIGRADE

The object of this paper is to describe the toughness properties of 9% Ni-steel at loading rates occurring in ship structures. The static fracture toughness of 9% Ni-steel has been studied extensively in the development stage of the Moss Rosenberg LNG-ships with spherical tanks. The dynamic properties, however, have been lacking, and it has been the aim of this investigation to compare the dynamic and static fracture toughness for a large number of production heats. The test results show that dynamic loading of the use rate has not significantly influenced the fracture toughness, expressed as K sub max-values, of the 9% Ni-steel.
