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.
