Inconel Bolts & Alloy 330 Bolts for Cyclic High Temperature Conditions

Q: I need a material that can stay oxidation resistant at 2000F in a cyclic temperature environment. Any suggestions?
A: One of the best choices is Inconel 601, UNS N06601,which is highly resistant to oxidation up to 2200°F and can handle even severe thermal cycling. These Inconel bolts will offer good high temperature strength and retain ductility after long service exposure. Also an excellent choice would be an Alloy 330 bolt. They offer oxidation and carburization resistance to 2100F – just over your requirement. Alloy 330 bolts are also known for their ability to withstand cyclic conditions of temperature extremes from heating and cooling. Which fastener is better, Inconel or Alloy 330, will depend on your strength requirements at temperature.

Inconel 600 Bolts vs. Inconel 601 Bolts

Q: Can you tell me what the difference is between Inconel 600 and 601? I need a material for high temperature thermal cycling.
A: Both Inconel 600 and Inconel 601 bolts are oxidation resistant at  high temperatures. The main difference is that Inconel 600 bolts have a maximum usable temperature of 2000°F, where Inconel 601 screws can be used at higher temperatures up to 2200°F. In addition, Inconel 601 bolts perform well in cyclic temperature conditions.
Another material to consider for cyclic conditions would be Alloy 330 which is very oxidation and carburization resistant to 2100°F. Plus,  Alloy 330 bolts are known for the ability to perform in cyclic conditions of temperature extremes.
