1. Question: What are the main features of Hastelloy X and Incoloy 800 alloy steel?
Answer:
Hastelloy X is a nickel-chromium-iron-molybdenum alloy known for outstanding resistance to oxidation and carburization at high temperatures, as well as good mechanical strength.
Incoloy 800 is a nickel-iron-chromium alloy that provides excellent resistance to oxidation, carburization, and stress corrosion cracking, especially in high-temperature environments.
2. Question: In which industries are Hastelloy X and Incoloy 800 commonly used?
Answer: Both alloys are widely used in aerospace, chemical processing, power generation, petrochemical, and furnace construction applications where high temperature and corrosion resistance are critical.
3. Question: What temperature range can these alloys withstand?
Answer:
Hastelloy X can operate continuously up to approximately 1093°C (2000°F) with excellent mechanical properties.
Incoloy 800 can handle temperatures up to around 1100°F (593°C) for oxidation resistance and higher temperatures in non-corrosive environments.
4. Question: What standards do Hastelloy X and Incoloy 800 conform to?
Answer:
Hastelloy X conforms to AMS 5798, AMS 5870, AMS 5871, AMS 5872 standards for chemical composition and mechanical properties.
Incoloy 800 typically conforms to ASTM B163, B407, and UNS N08800 standards.
5. Question: Why choose Hastelloy X or Incoloy 800 over conventional stainless steel?
Answer: Both alloys offer superior resistance to high-temperature oxidation, carburization, and corrosion, providing longer service life in extreme environments where stainless steel would fail or require frequent maintenance.
