CORROSION AND STRESS CORROSION OF HY-130(T) STEEL AND HY-80 STEEL IN MARINE ENVIRONMENTS

Abstract

For several years the Applied Research Laboratory has been engaged in developing a submarine-hull-steel weldment with a yield strength in the range 130 to 150 ksi. Because the coatings used for protecting submarine hulls from corrosion may become damaged during service and the underlying steel exposed to sea water, the knowledge of the corrosion and stress-corrosion properties of submarine-hull-steels is essential for characterization of the steel. Consequently, the ARL made studies to determine the corrosion and stress- corrosion properties of plain-plate and welded specimens of 5Ni-Cr-Mo-V steel- now designated HY-130(T)-along with HY-80 steel for comparison purposes, in various marine environments. Included were shallow-water exposure tests conducted at Wrightsville Beach, North Carolina, and deep-sea exposure tests conducted in cooperation with the U. S. Naval Civil Engineering Laboratory at Port Hueneme, California.
