Inconel Bolts for High Temperature

Q: I have an application that needs an alloy to withstand 2100° F with no preload. Would Hastelloy be a good choice?
A: Probably not. Hastelloy fasteners have a max usable temperature of 1500°F and is primarily used for corrosion resistance. For these temperatures Inconel bolts are a better choice as it is more stable at higher temperatures. If you have no corrosion resistant chemicals present you could also use Alloy 330 fasteners.
