ASTM Weathering Steel Specifications Central Steel ServiceASTM A709-50W. ASTM A709-50W is a standard specification for structural steel in bridges. ASTM A709-50W covers high strength, low allow steel structural shapes, plates and bars. The atmospheric corrosion resistance of this steel in most environments is substantially better than carbon steel with or without copper addition.

It will most often be produced by as-rolled or control-rolled practices. ASTM A709 also allows it to be Thermo-Mechanical Controlled Processed (TMCP), with or without accelerated cooling, normalized, quenched
High 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. Preheat and Interpass Temperature for - WELDING For ASTM A709 Grade HPS 70W and ASTM A852, the maximum preheat and interpass temperatures shall not exceed 400°F [200°C] for thicknesses up to 1-1/2 in [40 mm], inclusive, and 450°F [230°C] for greater thicknesses. The use of high heat input welding processes such as submerged arc welding (SAW) may allow for lower preheat temperatures
