We have a product in constant contact with fresh water consisting of
304 thin-wall tubing (0.3 mm thickness) welded to a 304 reducer of
about 3mm thickness. We are considering options to lower the
manufacuring cost by changing the reducer material. Our manufacurer has
suggested changing the reducer material to zinc-plated ASTM A53 carbon
steel.
1. Is it possible to weld this to the SS304 tubing without resulting
corrosion?
2. If not, is it possible to braze the SS304 tubing to zinc-plated
ASTM A53 without resulting corrosion?
3. Any suggestions on any other material for the reducer to lower
manufacturing costs in order to weld or braze the reducer to SS304
tubing? The tubing is flexible, and must be made of SS304.
Thanks for any help you can give.
