3、standard has been approved for use by agencies of the Department of Defense.1. Scope Scope*1.1 This specification covers high-strength low-alloy nickel, copper, phosphorus steel H-piles and sheet piling of structuralquality for use in the construction of dock walls, sea walls, bulkheads, excavations
4、, and like applications in marine environments.1.2 The atmospheric corrosion resistance of this steel is substantially better than that of ordinary carbon steels with or withoutcopper addition (see Note 1). The steel has also shown to have substantially greater resistance to seawater “Splash Zone” c
5、orrosionthan ordinary carbon steel (Specifications A36/A36M and A328/A328M) where exposed to the washing action of rain and thedrying action of the wind or sun, or both. Where the steel is not boldly exposed, the usual provisions for the protection of ordinarycarbon steel should be considered.NOTE 1
6、For methods of estimating atmospheric corrosion resistance of low-alloy steels, see Guide G101.1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended useor service will be utilized. See Appendix X 3X3 of Specification A6/A6M for in
7、formation on weldability.1.4 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shownin brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of theother. Combini
8、ng values from the two systems may result in nonconformance with the specification.2.
