Q: I’m working with a high temperature waste to fuel application that operates at 1000F normally but could spike to 1200F. Currently I am using Grade 8 bolts but I am concerned about the oxidation resistance of them and their stability at high temperatures.  Do you have any material recommendations? 

A: One of the best materials to consider for your high temperature application is A-286.  A286 bolts will be strong, oxidation resistant and thermally stable.  This will provide you will an significantly improved solution over Grade 8 alloy steel. An A286 bolt is also usable to 1300F.
