Inconel 600 Fasteners
Patriot Bolt machines Inconel 600 fasteners from certified ASTM B166 bar (UNS N06600). Alloy 600 is a nickel-chromium-iron alloy with at least 72% nickel, used for high-temperature oxidizing atmospheres, caustic service and chloride stress corrosion cracking resistance.
This page brings together the Inconel 600 fasteners we make, the bar property limits by condition, and how 600 compares with other nickel and corrosion-resistant alloys.

Inconel 600 vs. Other Nickel and Corrosion-Resistant Alloys
| Grade | Strength, min (tensile / yield) | Typical use |
|---|---|---|
| Inconel 600 (B166, annealed) | 80 / 35 ksi | High-temperature oxidation; caustic service |
| Inconel 625 (B446 Grade 1, annealed) | 120 / 60 ksi | Seawater, subsea and acid service |
| Inconel 718 (B637, aged) | 185 / 150 ksi | High strength at temperature; oil tools |
| Incoloy 825 (B425, annealed) | 85 / 35 ksi | Sulfuric and phosphoric acid; seawater |
| 316 stainless (A193 B8M Class 1) | 75 / 30 ksi | General corrosion resistance; mild chemicals |

Inconel 600 Fastener FAQ
What is Inconel 600 used for?
Furnace and heat-treating hardware, caustic and alkaline chemical service, and high-temperature joints where stainless steel would crack or oxidize.
Which Inconel 600 fasteners does Patriot Bolt make?
We machine Inconel 600 stud bolts, heavy hex nuts, heavy hex bolts and hex cap screws, as well as custom parts made to your drawing.
Can Inconel 600 be heat treated for strength?
No. Alloy 600 is not age hardenable. Higher strength comes from hot-worked or cold-worked bar, as shown in ASTM B166.
Do Inconel 600 fasteners come with certifications?
Yes. Patriot Bolt is ISO 9001:2015 certified, and every Inconel 600 order includes mill test reports traceable to the heat and a certificate of conformance to your purchase order.
