More than a dozen bridges in the United States have been built using HPS 70W grade steel, which has a yield strength of 485 MPa (70 ksi) but superior toughness compared to conventional grade 70 steel. Now that the material, known as high-performance steel (HPS), has proven worthy of its praises—which include 10 to 20 percent cost savings in some cases because less material is needed—the industry's HPS steering committee is pushing for code and standard development and manufacturing improvements to make the material even more cost-effective.
