MATERIALS
**************************************************************************
NOTE: Selection of material should be based on a
comprehensive study of strength, cost, and
corrosion-resistance requirements. ASTM A 36/A 36M
and ASTM A 572/A 572M steels have the same corrosion
resistance; ASTM A 572/A 572M can be obtained in
yield strengths of 290 MPa through 415 MPa (42 ksi
through 60 ksi). ASTM A 588/A 588M has twice the
atmospheric resistance of ASTM A 36/A 36M steel with
0.20 percent copper added. ASTM A 690/A 690M steel
(345 MPa (50 ksi) yield strength) has twice to three
times greater resistance to seawater "splash zone"
corrosion than ordinary ASTM A 36/A 36M steel.
Since ASTM A 690/A 690M steel offers little or no
advantage from a corrosive standpoint over carbon
steel when totally immersed in water or buried in
the mud, the designer may want to think in terms of
composite H-pile with the section exposed to salt
spray made of ASTM A 690/A 690M steel.
**************************************************************************
Piles shall be of sections, sizes, materials, and weights indicated. Pile
tips as driven shall be square and blunt as received from the mill. Pile
tip reinforcements or cast steel points occasionally may be required to
obtain the required penetration. Steel shall conform to [ASTM A 36/A 36M] [
ASTM A 572/A 572M, Grade [_____]] [ASTM A 588/A 588M] [ASTM A 690/A 690M].
The Contractor shall submit for approval details of fabricated additions
required for the piles. Test piles shall be identical to those used
elsewhere in the project.
