Frequently Asked Questions
What makes Inconel 601 Washer resist oxidation better than Inconel 600?
Added aluminum 1.00-1.70% creates a tough second oxide layer, letting Inconel 601 washers resist high-temperature scaling far better than Inconel 600.
Is Inconel 601 Washer magnetic?
It is essentially non-magnetic in the annealed condition, consistent with other nickel-chromium alloys in this family.
What makes Inconel 601 Washer different from Inconel 600 Washer?
Its added aluminum gives 601 superior oxidation resistance up to 1200°C whereas 600 excels in chloride and reducing environments.
