Re: A490 bolts

[Subject Prev][Subject Next][Thread Prev][Thread Next]
	Javier,
		ASTM A 490-93 (may not be the latest version) Section 5.4
reads, "The bolts shall not be hot dip, mechanically, or electroplated with
zinc or other metallic coatings as such bolts are subject to hydrogen
embrittlement with subsequent stress corrosion cracking and delayed brittle
failure in service."
