Embrittlement of grade 10.9 hot-dip galvanized fasteners




June 25, 2010

We are hot-dip galvanizing 10.9 grade fasteners.
Will pickling by phosphoric acid prevent or reduce hydrogen embrittlement on such jobs?

Shot-blasting is an option but the threaded portion may be damaged. also lead time after shot blasting and galvanizing is a concern

Sir:

What is the tin (Sn) content of your molten zinc bath?
