(OP)
I am looking for creep properties for Waspaloy beyond the 1000 hr data that seems to be generally available. Any ideas? Thanks.

RE: Waspaloy creep >1000 hr
Mind if I ask why? If this is a new design then you aren't using this alloy.
You must be working with some old equipment?

Did you try Haynes International or ATI (Allegheny technologies)?

RE: Waspaloy creep >1000 hr
I'm curious about your comments regarding use of this alloy for new designs/equipment. Are you assuming the product form to be plate/sheet/strip and the end use is a land-based gas turbine? My familiarity with this alloy is in the form of bar/rod/wire for high temperature fasteners used in aerospace gas turbines, of which this is still contemporary practice. The datasheet from Special Metals shows 14 different SAE AMS and AECMA PrEN standards for Waspaloy bar/rod/wire, and numerous aerospace manufacturers like SPS and Alcoa show "standard" products that they manufacture in Waspaloy.

There is a lot of spec coverage for 625 still too, but that doesn't make it state of the art.

Thanks for the additional information. Would you mind jotting down some of the alloys that have higher creep strength than Waspaloy? I'm curious if any of them are offered in bar/wire/rod for fastener applications. SPS offers Alloy 718 or the proprietary grade Aerex 350, but that is about it in terms of high temperature, creep-resistant grades.

See the attachment below. I started to compile some data but ran out of time. This is from a Gas Turbine Alloy Handbook.
