High strength steels have been available for years, but their use required more welding control and fabrication processes than conventional strength steels. A new grade of high performance steel, HPS-485W or HPS-70W, developed by a cooperative program between the Federal Highway Administration, the American Iron and Steel Institute, and the Department of the Navy in August 1994; uses a new chemical composition that provides improved welding and toughness properties.
