Hastelloy X

Material: Hastelloy X, UNS N06002, 2.4665
Hastelloy X is a nickel-based alloy with good oxidation and corrosion resistance, medium and long-lasting strength below 900°C, and good cold and hot processing formability and welding performance. It is suitable for manufacturing combustion chamber and other high-temperature components of aircraft engines, with long-term use below 900°C and short-term working temperature reaching 1080°C.

Hastelloy X Features

  1. Hastelloy X possesses an exceptional combination of oxidation resistance, formability and high temperature strength.

  2. It has also been found to be exceptionally resistant to stress-corrosion cracking.

  3. Alloy X exhibits good ductility after prolonged exposure at temperatures of 1200, 1400, 1600 °F for 16,000 hours.

  4. It has excellent formability and welding characteristics.

  5. Hastelloy X can be forged and, because of its good ductility, can be cold-worked.

  6. It can be welded by both manual and automatic welding methods including shielded metal-arc (coated electrodes), gas tungsten-arc (TIG), and gas metal-arc (MIG). Alloy X can also be resistance-welded.

Hastelloy X Application:

Hastelloy X is widely used in various high temperature environments due to its corrosion resistance in various atmospheres at high temperatures and its excellent high temperature strength.

  • Industrial and aviation steam turbines (combustors, rectifiers, structural covers).

  • Industrial furnace components, support rolls, grids, ribbons and radiant tubes.

  • Spiral tubes in petrochemical furnaces.

  • High temperature gas cooling nuclear reactor.

FAQs

Q1: Is Hastelloy X Magnetic?

A: Hastelloy X (UNS N06002) is non-magnetic in the annealed condition. However, cold working may induce slight magnetism from strain-induced martensite. In most cases the magnetism is almost non-existent.


Q2: Is Hastelloy X Precipitation Hardened?

A: No, Hastelloy X is solid-solution strengthened, NOT precipitation hardened.
