Inconel Alloys
Inconel 600 (UNS N06600) — Composition, Properties & Supply
Inconel 600 (UNS N06600) is a solid-solution strengthened nickel-chromium-iron alloy with at least 72% nickel and 14–17% chromium. It combines high-temperature oxidation resistance, resistance to chloride stress-corrosion cracking and good hot/cold workability, making it a classic choice for furnace components, chemical equipment and nuclear parts.

Frequently asked questions
How does Inconel 600 differ from 304 or 316L stainless steel?
Inconel 600 contains about 72% nickel versus roughly 8% in 304 and 10% in 316L. The high nickel makes it virtually immune to chloride stress-corrosion cracking and lets it resist oxidation above 1000 °C, while 300-series stainless risks SCC in chlorides above about 60 °C and is generally limited to 870 °C in air.
Which standards cover Inconel 600 mill products?
ASTM B166 for bar, B168 for plate/sheet/strip, B167 for seamless tube, B564 for forgings, plus AMS 5540/5665 for aerospace. Hangbo supplies to these specifications with EN 10204 3.1 certification.
Is Inconel 600 weldable and which filler metal should be used?
Yes. ERNiCr-3 (Inconel 82) is the standard TIG/MIG filler; submerged arc uses ENiCrFe-3 wire with a matched flux. Clean the joint thoroughly and keep interpass temperature below 150 °C.
