Abstract
An improved forged steel structure lined with a corrosion resistant metal in which the lining and body are forged together. The improved method includes the steps of securing a bar of corrosion resistant metal within an alloy steel tube to form a billet, forging the billet to the desired shape with sufficient corrosion resistant metal to line at least one of the cavities of the desired shape and machining the forging to produce the desired lined structure. The amount of alloy steel and corrosion resistant metal in the billet being preselected to provide the desired lining without substantially weakening the structure.
