Special Metals is the producer of Inconel alloys.  Their website is http://www.specialmetals.com/

"Inco 718", also known as "Inconel 718", a.k.a. "Alloy 718" is a fairly common nickel-chromium-iron alloy, sometimes called a nickel based superalloy.  TVP was right that Special Metals holds the tradename, and their datasheet is at

They also have a variant that is aimed at superplastic forming applications, and that information is at

Other companies make the same stuff: Allegheny Ludlum's information sheet is at

while CarTech's can be found on their website at www.cartech.com: "Pyrotool 7" is one of their tradenames.

After reading the brochure, you can direct your questions to the technical service department of one of the producers- I've always had good experiences talking over proposed applications with those folks.

Good luck!

Lee,

Excellent follow-up.  And here I was just shamelessly plugging Special Metals...

Does anyone know what the proper punishment for this offense is?

Hello, thank you for the response to everybody. I would like to know if the INCO718 or the equivalents is creepable forming.

Thank you

I believe you mean superplastic forming, so the answer to your question is yes.  Lee Gearhart gave you the link to the technical bulletin for the Inconel 718spf (superplastic forming) grade in his earlier reply.  I will copy it here:
