High Temp. Spring Materials

(OP)
I am looking for a material to create butterfly clamps (a.k.a. spring clips) that must withstand 1000 degrees Fahrenheit.  Anyone have any suggestions?

RE: High Temp. Spring Materials

Inconel 718 if you want to go first class. 1000F yield strength is 154,000 psi, room temperature is 172,000psi.
If cost is more important try 316 stainless.
