Nitronic 40
Nitronic 40, as known as 21-6-9, is an austenitic stainless steel that has been designed to be an extremely strong alloy in the annealed condition, to have excellent resistance against oxidation at elevated temperatures, and to have superior toughness even at cryogenic temperatures. Products manufactured from this material are either melted using one of two processes: AOD (Argon Oxygen Decarburization) or AOD + ESR (Electroslag remelting).
Applications of Nitronic 40
Nitronic 40 is suitable for high-performance and demanding applications, including:
- Aircraft engine components requiring both corrosion resistance and strength
- Pollution control equipment such as scrubbers and stacks
- Chemical processing systems with exposure to oxidizing and corrosive environments
- Cryogenic vessels and components due to exceptional low-temperature toughness
Material Properties
Key properties of Nitronic 40 include:
- Creep resistance at elevated temperatures
- Excellent oxidation resistance
- Superior toughness at cryogenic temperatures
- High yield and tensile strength in annealed condition
- Good weldability and formability
Certified Material for Critical Service
Nitronic 40 is certified for critical service applications, ensuring that all material supplied meets strict aerospace and industrial standards. Each batch is fully traceable with certification, guaranteeing compliance with AMS 5656, AMS 5595, and other relevant standards.
This certification confirms Nitronic 40 as a reliable choice for highly stressed components where failure is not an option, including turbine parts, structural components, and chemical process equipment.
