Just as a matter of interest, the "Nickel Development Institute" provides free information on any Nickel containing alloy. The website is www.nidi.org and you can order a lot of free information books as well. All you do is ask for them, and they send them out right away. They also have phone numbers and contact information for engineers that specialize in nickel alloys. If you needed an alloy for a specific process, you can give them the variables and they will suggest alloys for your application. I have used them a few times, they are a really valuable contact. They are based in Toronto, Ontario, Canada. Try them out.
