Abstract:

A study was made of the mechanical properties and weldability of a steel composition which was judged to show promise as a steel for heavy-section ship plate. The steel was chosen on the premise that a simple carbon-manganese steel could be heat-treated to furnish the desired properties including weldability at a lower cost than that of more complex alloy steel grades. Broadly, the steel in thicknesses up to 3 inches was expected to possess the strength, resistance to brittle fracture, and weldability equal to 2-inch normalized ABS Class C steel. While the laboratory tests could not be used to determine the service properties of the steel, they provided a direct comparison of the steel to ABS Class C, whose characteristics and service performance are well-known.
