    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. This means that HPS 70W(HPS 485W) remains fully ductile at lower temperatures where conventional Grade 50W steel begins to show brittle behavior.sp.info High Performance Steel For Highway BridgesHigh Performance Steel has much higher fracture toughness than the conventional grades of steel used for bridge construction. Figure 1 shows the Charpy V-Notch (CVN) transition curves for HPS 70W and conventional AASHTO M270 Grade 50W steel. The brittle-ductile transition of HPS occurs at a much lower temperature than conventional Grade 50W steel.sp.info Structural Steel Specification - Codes and standards Mar 01, 2011 · However, everytime you see a reference to bridge structural steel, you'll see AASHTO M270/ASTM A709 which to me means they are one in the same.
