Corrosion Resistant Bolts for Submerged Applications
Corrosion Resistant Bolts for Submerged Applications
(OP)
I need to find out where I can obtain corrosion resistant bolts or coatings for bolts. This is my problem: I am installing bolts in a handrail which is being bolted to concrete. The bolts are installed inn water with a fairly high chlorine content. So far, the bolts we have tried have failed. LOTS of rust!
What can I do?

Fore more information on advanced alloys, I recommend you read the following article on multiphase fastener alloys from SPS:
http://www.spstech.com/aero/news/090602.html
They also have an excellent booklet on these alloys called Superalloys Developed by SPS Technologies for Aerospace Fasteners which you can obtain by clicking on the following link:

The following technical article on the AvestaPolarit website on bolt performance in seawater that may be useful:

And lastly, the November issue of Advanced Materials & Processes (http://www.asminternational.org/Template.cfm?Section=Magazines&NavMenuID=701) featured an article on Inconel 686 for marine fasteners. More information is available from Special Metals using the following link:
