ASTM A 690/A 690M - 00a Standard Specification for High-Strength Low-Alloy Steel H-Piles and Sheet Piling for Use in Marine Environments

American Society for Testing and Materials (ASTM). 2000, 2p. A 690/A 690M-00a
This specification deals with the standard structural quality of high-strength low-alloy nickel, copper, phosphorus steel H-piles and sheet piling for use in the construction of dock walls, bulkheads, excavations, and like applications in marine environments. The steel shall be semi-killed or killed and shall be exposed to the washing action of rain and the drying action of wind or sun, or both to determine its atmospheric corrosion resistance. Material specimens shall undergo product analysis, heat analysis, and tension testing and shall conform to the required chemical composition, tolerance, tensile strength, yield point, and elongation specifications.
Scope
This specification covers high-strength low-alloy steel H-piles and sheet piling of structural quality for use in the construction of dock walls, sea walls, bulkheads, excavations, and like applications in marine environments.
The steel has approximately two to three times greater resistance to seawater Splash Zone corrosion than ordinary carbon steel (Specifications A 36/A 36M and A 328/A 328M) where exposed to the washing action of rain and the drying action of the wind or sun, or both. Where the steel is not boldly exposed, the usual provisions for the protection of ordinary carbon steel should be considered.
When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X 3 of Specification A 6/A 6M for information on weldability.
The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification
