I was wondering if anyone would provide me with references in regard to the chloride SCC resistance of A-286. The bolting would be used in a costal enviroment. We currently are using 17-4PH which has had good service since 1992. All the reference material I currently have deals with the SCC of A-286 in borated water. I would appriciate any suggestions.

A-286 bolting will not be used in sea water. Just in an area on the coast. I was just looking for whether or not A-286 had better or worse SCC resistance to chlorides compared to 17-4PH. If it had equivalent resistance or better, which references would I be able to buy. Thanks, Chris
