3 Materials Design Guide for Bridges for Service Life Weathering-grade steels are currently supplied under AASHTO Specification M270, ASTM A709 Grade 50W, and in high-performance steel Grades HPS 50W, 70W, and 100W. These steels have a special alloy composition with small amounts of copper, phos- phorus, chromium, nickel, and silicon that makes them able to resist corrosion with- out any applied
The steel can meet the strength and impact proper- ties of AASHTO M270 Grades 50W and HPS 50W up to a thickness of 4 in., making it an attractive steel for traditional plate girder bridges. 6.2.6 Description of Weathering Steels Uncoated weathering-grade steels contain small amounts of copper, phosphorus, chro- mium, nickel, and silicon to
751.50 Standard Detailing Notes - Engineering_Policy_GuideMar 25, 2021 · Structural steel for sole plate shall be ASTM A709 Grade 50W and shall be coated with a minimum of two coats of inorganic zinc primer to provide a total dry film thickness of 4 mils minimum, 6 mils maximum. The welds shall have corrosion resistance and weathering characteristics compatible with the base material.
