The HPS Fab Guide is recommended for use until such time that other industry codes and specifications have included this product and have provided the necessary regulatory provisions to successfully fabricate bridges. The 2nd Edition is based on High Performance Steel Designers' GuideThis is evident from Figure 2.3.1, which shows the Charpy V Notch (CVN) transition curves for HPS 70W(HPS 485W)and conventional AASHTO M270 Grade 50W steel. The brittle ductile transition of HPS occurs at a much lower temperature than conventional Grade 50W steel.
