ASTM A690 (or, Mariner Steel) was created and promoted by US Steel in the 1960s. At the time there was no grade of steel higher than A328 (39 ksi yield strength), and the US Steel sheet piling literature focuses on the fact that, as a stronger grade of steel, A690 (50 ksi yield strength) will be stronger longer than A328 once corrosion sets in (for any environment).
ASTM A252 Pipe Piles Specifications (Grade 2, 3) - Octal SteelASTM A252 standard specifications covers the steel pipe piles manufactured in seamless and welded, shapes in cylinder as a shell for filling with the concrete. It has been widely used in construction, structural, bridge buildings that required solid base. Most common piling material is ASTM 252 Grade 3 pipe pile.
Pipe piles can be fabricated as extruded or rolled thin-walled pipe piles, spiral welded steel, extruded steel, and rolled steel (ASTM A252, Standard Specification for Welded and Seamless Steel Pipe Piles). The available size range of pipe piles and the stiffness that can be increased by increasing the pipe wall thickness has made them desirable for major bridge foundations.
