A286 Bolts for High Temperature Annealing Oven

Q: I have require fasteners for use in an annealing oven for aa centrifugal fan (@1725 RPM) attached to a shaft with a through bolt and nut (shaft and fan are both SST). The environment is 1275 degrees F at atmospheric pressure and runs continuously 5 days a week I require fasteners that will have a long service life, but easily removable for maintenance. Ideas?

A: For a high temperature application such as this, you might want to consider A286 bolts and nuts. A286 is a high temperature stable and very strong steel. Often used in high temperature turbines and exhaust applications, these bolts will retain their strength to 1300°F .

If you combine this with our Moly-Disulphide anti seize (if that is OK in your application) you will have no problem getting them off. .
