We are currently designing a high strength structural bracket for service above the water line on the back of ocean going vessels (operating just about everywhere)
For various reasons it's desireable to use a modestly corrosion resistant alloy, and historically we've used 17-4 PH H1075 stainless for this type of service.
We're currently considering a cast solution instead of the welded/machined parts we normally use. The first material candidate is CB-7Cu-1, however we're interested in comparing it to other options, which may have different combinations of strength, castability, corrosion resistance and price.
Our local vendors have limited experience with marine conditions, and with the exception of a small number of austenitic and duplex grades, we have limited experience with stainless castings. Can anyone suggest a good reference text for high performance marine grade casting alloys, or alternatively suggest a few candidate alloys we might consider looking at?
Thanks for any suggestions!
