Abstract : High Performance Steels (HPS) for highway bridge applications are being developed under a cooperative agreement between the FHWA, the AISI and the U.S. Navy. This combined and coordinated effort has culminated in the production of low carbon weathering steels which exhibit excellent strength, toughness and weldability at the 485 MPa (70 ksi) and 690 MPa (100 ksi) yield strength levels. The production heats of these HPS's meet the current mechanical property requirements of ASTM A709 Grades 70W and 100W. This paper presents the development of the steels produced under the FHWA Program on High Performance Steels for Bridge Construction.
