Nickel Alloy Hastelloy X N06002 Gasket Rings Critical Seals in Aerospace Equipment
Hastelloy X, also known by its UNS designation N06002, is a nickel-chromium-iron-molybdenum alloy that exhibits an exceptional combination of oxidation resistance, fabricability, and high-temperature strength. This makes it highly suitable for applications in the aerospace, industrial gas turbine, and chemical processing industries.
Physical Properties:
- Density: 8.22 g/cm³
- Melting Range: 1355-1413°C (2471-2575°F)
Heat Treatment:
Hastelloy X can be strengthened by cold working or by heat treatment, with a typical annealing temperature of around 1177°C (2150°F) followed by rapid cooling to optimize its performance.
Corrosion Resistance:
Hastelloy X offers excellent resistance to oxidation at high temperatures, making it suitable for use in furnace and combustion chamber applications. It has good resistance to reducing and carburizing environments, although it is not as resistant to corrosion by aqueous solutions as some other Hastelloy grades.
Applications:
- Furnace parts such as conveyor belts, rollers, fans, and fixtures in heat-treating applications
- Gas turbine engine parts including combustion zones, transition ducts, and afterburner parts
- Components in petrochemical and chemical processing industries where high-temperature resistance is required
Specifications and Standards:
The production and use of Hastelloy X gasket rings must comply with specific standards to ensure their reliability and performance. Commonly applied standards include ASTM B435, B572, AMS 5536, 5754, and others relevant to nickel alloys.
Features and Fabrication:
- Hastelloy X is known for its excellent formability and weldability.
- It can be welded using various techniques, including gas-tungsten arc welding (GTAW), shielded metal arc welding (SMAW), and gas metal arc welding (GMAW).
- The alloy’s high-temperature strength also means it retains its ductility after prolonged exposure to extreme conditions.
In essence, Hastelloy X (N06002) gasket rings are designed to withstand severe high-temperature environments and corrosive conditions, ensuring reliability and longevity in the most challenging applications. Given its specialized characteristics, this material is often selected for critical seals in aerospace, power generation, and chemical processing equipment.
