stainless steel vs hot dipped galvanized
stainless steel vs hot dipped galvanized
(OP)
I have a job were I have to distinguish stainless steel brick ties from hot dipped galvanized ties.
Is there any simple test that can be done on a construction site to determine if a tie is stainless steel or not?
Or this kind of tests can be perfomed only by specialized labs?
Thank you

RE: stainless steel vs hot dipped galvanized
Another way would be to apply a drop of hydrochloric acid to the part. The galvanized part will have hydrogen gas evolved (bubbles in the liquid drop) due to reaction with the zinc, while the stainless will be unaffected.

Try the magnet first, but doubt that the SS ties are fully nonferromagnetic.
Acid may be your only option.
