A 252 Grade 2 for piles??

[sayee1]

1. Any idea on why this material is used for piles, i.e. A252 Grade 2. from what I can see of the amterial it says low carbon steel but from the specs P0.05 and rest Fe. I am confused on whether this is nearly pure Iron or steel.
2. In some technical write up I saw, since this material is not listed in AWS D1.1, they have aswked for this material to be welded considering it an equivalent to A572 Gr 50? Any thoughts on this.
3. If I were looking for a metrial substitute on basis of YS and UTS alone, I can use API 5L Grade B or A36. But is YS and UTS the only things to be considered for the applications that this material intended for namely piles......
An urgent reply would be appreciated.

The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.

In addition, the piles we have are for a bridge over water
