The National Shipbuilding Research Program 1985 Ship Production Symposium Volume 2 Paper No. 4: Higher Strength Steels Specially Processed for High Heat Input Welding

Abstract

ABS Grade EH36 steel plates, specially formulated and produced with advanced metallurgical techniques are shown to have a significantly greater resistance to weld heat affected zone (HAZ) degradation than conventional EH36 steel. Welds made in these steels with the electroslag welding process at high heat input rates retained adequate toughness in the heat affected zone at -40F (-2O%C); similar welds in conventional EH36 steel plate exhibit excessive HAZ toughness loss. The above was confined on the basis of small scale Charpy V-notch and large scale explosion bulge testing. In view of their superior resistance to HAZ degradation, the steels should also be useful for applications where HAZ degradation is of particular concern, such as for ABS, Coast Guard and International Maritime Organization (TMO) weld requirements for Liquefied Gas Carriers.
