Abstract : In accordance with the present invention, an alloy steel is provided which exhibits a high Charpy V-notch shelf energy and a low transition temperature. Its asquenched microstructure contains significant amounts of bainite thereby allowing a substantially lower carbon content. The combination of low carbon content along with moderate alloy content results in a low tendency toward HAZ cracking and a superior steel for producing various types of structural weldments for use as submarine hulls, ship hulls, tanks, etc.
