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. Heat analysis shall be used to determine the percentage of carbon, manganese, phosphorus, sulfur, silicon, and copper for the required chemical composition. Tension test shall be used to determine the required tensile properties such as tensile strength, yield strength, and elongation. Materials shall undergo: (1) impact test for non-fracture critical and fracture critical members; and (2) Brinell hardness test for Grades 100 and 100W. Atmospheric corrosion resistance shall also be determined.
