Validation of Nitronic 33 in Reinforced and Prestressed Concrete
Nitronic 33 stainless steel has a unique combination of high strength and nonmagnetic properties which make it an excellent candidate for use as prestressing strand for concrete waterfront structures where the magnetic properties of the carbon steel commonly used for prestressing strand are not acceptable. Before Nitronic 33 stainless steel prestressed concrete waterfront structures were constructed, it was necessary to establish the corrosion performance of the Nitronic 33 stainless steel in marine concrete. A test plan was developed where a series of tests which compared the performance of carbon steel to the Nitronic 33 stainless steel were to be performed. The time to initiation of attack was established as the critical parameter for the evaluation of the test results. In each test, corrosion of the carbon steel initiated prior to the initiation of the corrosion of the Nitronic 33 stainless steel. In addition, previously emplaced fullscale pier pilings with both carbon steel and Nitronic 33 stainless pretressing were inspected. The corrosion activity of the Nitronic 33 stainless steel prestressed piling was less than that of the companion carbon steel prestressed pilings.
