Paper presented at the The First ISOPE Pacific/Asia Offshore Mechanics Symposium, June 24–28, 1990
Paper Number: ISOPE-P-90-133
... to be discussed [2] [l] [5]. The steels for icebreakers are required to have (i) high resistance to local corrosion in seawater, (ii) high toughness at low temperature and (iii) good weldability. In this paper, the local corrosion of high strength steel of Y.P. 440 N/mm 2 class manufactured by a...

Paper Number: ISOPE-P-90-119
... ABSTRACT: The higher strength steels often show HEAT-AFFECTED ZONE (HAZ) softening. In the previous study, it was shown that CTOD toughness is much more important than strength matching to get higher welded joint performance in a stress concentrated region on the basis of the FEM analysis and...

... Zone) in the HAZ. Factors influencing the microscopic toughness of the LBZ and measures to prevent low CTOD value have been studied (OMAE, 1988),(OMAE, 1989) and new steels which have high HAZ CTOD value have been developed (e.g. Chijiiwa et aI, 1988). For improving the LBZ toughness, selection of...

Paper Number: ISOPE-P-90-121
... ABSTRACT: Toughness and microstructure of HSLA welds reheated by successive welds was studied. Toughness changes can be classified into four categories by attained peak temperature. The causes of embrittlement are increasing of GBF, MAC, and effective grain size and the main governing factors...

Paper Number: ISOPE-P-90-122
... ABSTRACT: While recently developed platform steels have excellent low temperature toughness properties they may be nevertheless, susceptible to cleavage fracture initiation at focally brittle zones (LBZ" s) developed in coarse grain heat affected zones (CGHAZ" s) of welds. Current offshore...

... ABSTRACT: The demand of high strength steel for ship and offshore structure application has been changed from conventionally heat treated steel to TMCP steel, because the latter provides the improved strength - toughness balance and weldability. Enhanced property of TMCP steel comes from the...
