High temperature 718 inconel springs
(OP)
I wish to use inconel belville washers at up to 600 C for preloading a flange gasket seal. Does anyone have any data on time dependant effects at this temperature for 718 Inconel? I'm not sure of the heat treatment, but they are as received from Solon mfg.

For creep data at temps up to 898K, see: M.C. Chaturvedi (U. Manitoba), "Creep Deformation of Alloy 718," in the book "Superalloy 718. Metallurgy and Applications," E.A. Loria (ed.), TMS, (Warrendale, PA; 1989).

Another excellent compilation of information (although definitely not free) is the "Aerospace Structural Metals Handbook" (see: http://mpho.www.ecn.purdue.edu/MPHO/CRDA_Handbooks/asmh).
