DEVELOPMENT AND CERTIFICATION OF HSLA-100 STEEL FOR NAVAL SHIP CONSTRUCTION

A significant tonnage of HY-100 steel has been used in the structural designs of new ships and submarines for weight reduction, replacing the HT and HY-80 steels previously used. A reduction in hull fabrication costs and higher productivity can be achieved by substitution of an HSLA steel for HY-100. The significant factor in cost savings through use of HSLA steel in fabrication is the reduction or elimination of preheat for welding. Based on the success of the HSLA-80 steel system, a program was initiated to develop and certify an HSLA-100 steel as a replacement for HY-100. The alloy development and evaluation to support the certification of HSLA-100 steel plate and weldments for surface combatant structural and ballistic protection applications are summarized.
