Doc,
For comparitive purposes, Dillsburg Aeroplane Works in Dillsburg, PA
sells 2" od x 0.188" wall 4130 Cr-Mo tubing for $9.00 per foot.
This is raw Cr-Mo steel, not galvanized.
If you do not galvanize the mast it will slowly rust; however, its unlikely
to lose any significant strength in your lifetime or mine. You can paint
the mast to delay the rust process. Beware: a painted or galvanized
2" od mast will not fit into a 2" thrust bearing!
73!
