ASTM A709/A709M-07 Standard Specification for Structural Steel for Bridges. 1.1 This specification covers carbon and high-strength low-alloy steel structural shapes, plates, and bars and quenched and tempered alloy steel for structural plates intended for use in bridges. Nine grades are available in four yield strength levels as follows:
ASTM-A709 Standard Specification for Structural Steel Grade 50W [345W], or HPS 50W [HPS 345W] shall not be substituted for Grades 36 , 50  or 50S [345S] without agreement between the purchaser and the supplier. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
M270 vs. A709:Grade Comparison Leeco Steel, LLCOct 13, 2020 · Both M270 and A709 have weathering grades represented by a W, as with A709 Grade 50W which contain additional alloys that help them better endure extreme weather conditions. A709 also has high-performance standard (HPS) grades, which offer a balance of strength, weldability, corrosion resistance and ductility.
ASTM A709-50W is a standard specification for structural steel primarily in the fabrication of steel 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.
