Oxidation Resistant A286 and Alloy 330 Bolt

Q: I was reading that high temperatures will accelerate the rusting of metal bolts. Is there a material that can prevent this. I’m using the screws at 1300F intermittently.
A: What you are looking for is an oxidation resistant bolt. When a metal oxidizes it is attacked by oxygen which accelerates at high temperatures. Depending on the strength requirements of your application but Alloy 330 bolts and A286 bolts are ideal for preventing oxidation, hence rust at high temperatures. They also work well for 1300F of intermittent heat.
