Are the stanchion made of Stainless Steel?

The reason I have not simply replaced them is because I cannot remove
them.
The stanchions are welded to the bases, which are through-bolted to
backing
plates under the deck and behind the cabinetry and glassed in from the
inaccessible bottom. This boat (O'Day 37) is full uf such cuties, built as
if
it were never meant to have things replaced, like wiring, which is
sandwiched
between the gelcoat head liner and the bonded outer deck.

I have been toying around with ideas involving angle- or T-iron and big
screws, like jacks.
