May 17, 2019 · Structural Steel (AASHTO M270/ASTM A709) All structural steel will be AASHTO M270/ASTM A709 Grade 36 (F y = 36 ksi) or Grade 50 (F y = 50 ksi) and structural steel HP piling will be AASHTO M270/ASTM A709 Grade 50S (F y = 50 ksi) except where weathering steel (AASHTO M270/ASTM A709 Grade 50W steel) is indicated on the Design Layout or in special cases. See ASTM A709 - SSABASTM A709. The ASTM A709 is the Standard Specification for Structural Steel for Bridges and encompasses carbon, high-strength low-alloy, and quenched and tempered alloy steels used as structural plates in the construction of bridges. SSAB offers the following five grades of A709; 36, 50, 50W, HPS 50W and HPS 70W.
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. ASTM Welding Procedures A645 to A930When welding low alloy 1 1/4 Cr 1/2 Mo and 2 1/4 Cr 1 Mo with up to 0.05% max carbon, typically 8018-B2L / 9018-B3L (L = low carbon) can be used. When welding higher strength alloys or when tempering and quenching are required to attain the higher strengths the higher carbon 8018 B2 and 9018 B3 electrodes are utilized.
