Steels conforming to ASTM A709 HPS 50W or 70W with carbon contents 0.10 percent or less are exempted from this rule. The engineer may allow steels with up to CE 0.58 only if the contractor uses an engineer-approved adjusted welding procedure. Submit steel mill certifications indicating the composition of the steel provided under the contract.

The American Association of State Highway and Transportation Officials (AASHTO) oversees the specifications of M270 steel plate, while ASTM oversees the specifications of A709 steel plate.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.

Role of Yield-to-Tensile Strength Ratio in the Design of ASTM A709-Grade 50 steel and HPS-690W(100W) 19 mm steel plates. Sause and Fahnestock (2001) reported tensile stress-strain relationships for HPS-100W steel. Their results consist of six tests from flange plates of 19 mm (3/4) thick, and four tests from web plate of 10 mm (3/8).
Nucor-Yamato Steel. Also, ASTM A992 now has an equivalent bridge steel, grade ASTM A709 Grade 50S. The inclusion of a maximum yield strength and a maximum yield-to-ten-sile strength ratio assures material ductility, particularly important in high-seismic applications (when R is greater than 3).
