A514 (T1) Galvanizing / Embrittlement?
(OP)
Yea or nea on galvanizing A514 steel (T1). The application is un welded, burried in the dirt sections are relatively thin (easily galvanized).
Does anybody know of a good reference or have experience? My local galvanizer can't help.
Thanks, Tony

The galvanizing bath is 850 to 1,000 degrees F. The local galvanizer tends to go on the higher side because it ups his production rate. Distortion is not a problem in this application.
It will be used underground as a part of an anchorage system. The user expects to deploy the system in a wide variety of soil conditions, hence the desireability of the galvanizing. Because of the variety, there is no range of resistivity of the soil ahead of time.
Rated stress level will be 50 ksi (rated) and 10 to 25 ksi (working). The yield of the A514-B is 100 ksi.

Your galvanizer needs to be on top of the acid bath chemistry with the correct inhibitor level to prevent hydrogen formation.
