Key Advantages of UNS N06002 Round Bars
High Temperature Oxidation Defense
Balanced chromium (20.5–23%) and iron (17–20%) form a protective oxide scale that resists spalling and oxidation up to 2200°F (1200°C).
Creep & Stress-Rupture Strength
Solid-solution strengthening from molybdenum (8–10%) and cobalt provides exceptional mechanical resistance to high-temperature deformation under continuous thermal load.
Carburization & Nitriding Resistance
Outstanding resistance to reducing or carburizing atmospheres, protecting critical furnace hardware and heat-treating components from embrittlement.
Excellent Fabricability
Good ductility (35% min) allows cold forming and machining, while maintaining resistance to strain-age cracking during welding and post-weld fabrication.
Key Applications of Hastelloy X Round Bars
| Industry Sector | Typical Components | Operating Conditions |
|---|---|---|
| Aerospace & Gas Turbines | Combustion cans, transition ducts, spray bars, and tailpipes | Continuous extreme heat up to 2200°F, high-velocity exhaust gases, and thermal stress |
| Industrial Furnaces | Retorts, furnace baffles, conveyor rolls, and support grid bars | Carburizing and oxidizing atmospheres, high thermal cycling |
| Petrochemical Processing | Pyrolysis tubing supports, reformer components, and catalyst grids | High-temperature gas cracking, sulfur-bearing atmospheres, and thermal stress |
| Nuclear Engineering | High-temperature gas-cooled reactor core components | Extreme thermal environments, helium gas coolant exposure |
| Industrial Heating | Burner tips, radiant tubes, and thermocouple protection sheaths | Direct flame impingement, aggressive thermal cycling, and high-heat gases |
Quality Testing & Inspection
Every batch of ASTM A479 Hastelloy X Round Bars supplied by Aurum Overseas undergoes rigorous testing:
- Positive Material Identification (PMI): XRF testing verifies exact elemental concentrations of nickel, chromium, iron, molybdenum, and cobalt.
- High-Temperature Tensile Testing: Evaluates yield and tensile properties at elevated operating temperatures to ensure design limit compliance.
- Ultrasonic Inspection: Volumetric testing per ASTM A388 confirms internal soundness free of micro-voids, cracks, or forging bursts.
- Dimensional Verification: Laser micrometers guarantee strict adherence to ISO h8 to h11 tolerance limits.
