Alloy 600 · UNS N06600
An Inconel 600 washer is a flat or spring ring that spreads bolt load. Finished fastener specification not asserted; material and manufacturing route not asserted — alloy (UNS N06600), dimensions and finished requirements are to the purchase specification. Flat washers protect the joint surface and spread load; spring and lock washers resist loosening. Match the washer material to the bolt to avoid galvanic corrosion.

Inconel 600 Washer: Why 600 for washers
Flat washers protect the joint surface and spread load; spring and lock washers resist loosening. Match the washer material to the bolt to avoid galvanic corrosion. In Inconel 600, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Nickel-alloy fasteners match nickel-alloy flanges in corrosive or hot service. Inconel 600 is picked for high-temperature oxidation, caustic and nuclear service. |
|---|---|
| Typical service | Furnaces & heat treating — Muffles, retorts and radiant tubes. |
| Bolting | B7 (coated), B8M or nickel-alloy studs in Inconel 600 (bar to ASTM B166, where applicable), as the project specifies |

Inconel 600 Washer — questions buyers ask
Do I need washers on flange bolting?
Many specifications require through-hardened washers under nuts for controlled tightening; follow the project bolting spec.
What nut is used with Inconel 600 washers?
Usually a nut in the same alloy — it may be machined from ASTM B166 bar, where applicable; finished requirements are to the purchase specification or project drawing.
Which standard covers Inconel 600 washers?
Finished fastener specification: Not asserted. Material / feedstock: Not asserted — alloy (UNS N06600), dimensions and finished requirements are to the purchase specification. Dimensions: ASME B18.22.1 · DIN 125 (legacy DIN). State the finished specification, material and dimensions on your purchase order or project drawing.
What decides the price of a Inconel 600 washer?
