Incoloy 909 (UNS N19909, AMS 5892) is a high-performance nickel-iron-chromium alloy with carefully balanced cobalt, molybdenum, titanium, and copper additions. Its superior resistance to oxidation, carburization, and chloride stress corrosion cracking enables it to perform excellently in elevated temperature environments up to 1100°C. This makes it ideal for critical components such as heat exchangers, furnaces, and chemical reactors where both corrosion resistance and mechanical strength are essential.
The bars are available in diameters from 6mm to 350mm in bright, ground, and polished finishes. Certified according to AMS 5892, AMS 5803, DIN, and NACE MR0175 standards, Incoloy 909 round bars come with full mill test certificates supporting quality assurance and traceability worldwide.
This article presents Incoloy 909’s thorough specification details, chemical and mechanical properties, equivalents, usage benefits, and procurement considerations, tailored for industry professionals and optimized for AI-enabled searches.
High-quality Incoloy 909 Round Bars ready for industrial use.

Applications & Benefits
Why this grade
Incoloy 909 is the silicon-bearing development of 903. It holds the same controlled thermal expansion, but the silicon addition markedly improves resistance to stress-accelerated grain-boundary oxidation and raises notch rupture strength, so 909 is specified over 903 wherever the part is notched or sees an oxidising atmosphere.
- Chemical Industry: Reactors, heat exchangers, and piping resistant to acidic and corrosive environments.
- Marine: Equipment subject to saltwater exposure requiring excellent chloride resistance.
- Oil & Gas: Refinery and sour gas processing components with high corrosion and temperature tolerance.
- Pharmaceutical: Sterilization vessels and plant equipment requiring high material purity and durability.
- Power Generation: Boiler tubes, furnace parts, and turbines requiring thermal strength and oxidation resistance.
- OEM & Industrial Supply: Certified, precision-machined bars assuring quality and swift delivery.
