Well, the price differential isn't that high, if you don't buy SS wire
that is preceded by the six most expensive letters in the English
alphabet; M A R I N E.

The basic material is more costly, and great deal more galvanized is used
throughout the world, cranes, tow cable, highway restraint cable, antenna
guys, drilling derricks......etc.


Properly cared for galvanized will out last steel, take an old boat
restoration class or two, ignore Wilbur/Neal, he knows nothing about
boats.

Bernard Boitessier rigged Joshua with galvanized wire and wood poles.
Worked for him. Not exactly light or pretty but worked.

Galvanised rigging looks perfectly OK but will start to rust after a year or
two. However this rusting is easy to check, since it will almost always
start at the lower ends of the shrouds where salt spray reaches it most
often. For this reason you mut periodically remove the seizing from the
splice at the lower end to make sure that hidden rust has not started inside
the splice.
