3308.1SCOPE
Provide steel for structural applications referenced in 2471, “Structural Metals.”
3308.2REQUIREMENTS
A General Provide steel for structural applications meeting the requirements of ASTM A6, Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling, and the following: B Quality Submit a Nonconformance Report (NCR) to the Engineer for review and approval before performing any weld repairs of the base metal.
Correct injurious defects (e.g. pipes, seams, unapproved repairs, laminations, cracks, segregations) and perform necessary testing to determine the extent of the defects or confirm the adequacy of repairs, as required by the Engineer, at no additional cost to the Department. The Engineer will reject plates or rolled beams with defects that reduce the thickness of the Material in any given section by greater than 30 percent.
3308.3SAMPLING AND TESTING
A Tensile Test Take tensile specimens for rolled beams from the mid-thickness of the flange and oriented longitudinally to the rolling direction. Note the location and orientation of tensile specimens on the mill test report. B Impact Tests Perform impact tests for structural steel provided for use in major structural components as defined in 2471.1A, “Definitions,” major structural components, or the Contract. The Department will not require impact testing for minor structural components unless otherwise required by the C ontract. Ensure that impact tested structural steel meets the requirements of ASTM A709, Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe, for Zone III Material.
