FAQs

Can Inconel 800 fasteners be used in corrosive chemical environments?

They offer moderate corrosion resistance compared to 625 or 718. Best suited for oxidizing atmospheres, mildly acidic or alkaline solutions, but not ideal for strong chloride or sour gas environments.

Can Alloy 800 fasteners be welded?

Yes, they can be welded using nickel based filler metals

How does Nickel 800 Bolts handle thermal cycling?

Inconel 800 fasteners perform exceptionally well under rapid heating and cooling cycles
