Study of the Factors Which Affect the Adequacy of High-Strength, Low Alloy Steel Weldments for Cargo Ship Hulls

Abstract

High-strength, low-alloy quenched and tempered steels of 100,000-psi minimum yield strength are being used in ship hull structures. A project was initiated by the Ship Structure Committee to define which mechanical properties should be used as performance criteria, to evaluate the suitability of these criteria with large-scale test weldments, and to select small-scale laboratory tests that correlate with the large-scale tests. A survey of available mechanical property data and of the use of these materials at various shipyards led to the recommendation that certain laboratory investigations be conducted. The report describes the results of both small-scale and large-scale tests conducted on high-strength, low-alloy plate and weldments.
