Incoloy Alloy 800 is a widely used structural material for equipment that must have high strength and resist oxidation, carburizing and other harmful effects of high temperature exposure (for high temperature applications requiring optimal creep and fracture properties, use Incoloy Alloy 800H and 800HT).
The major differences between alloys 800, 800H and 800HT are mechanical properties. The differences stem from the restricted compositions of alloys 800H and 800HT and the high-temperature anneals used for these alloys. In general, alloy 800 has higher mechanical properties at room temperature and during short-time exposure to elevated temperatures, whereas alloys 800H and 800HT have superior creep and rupture strength during extended high temperature exposure.

Why Incoloy 800/800H/800HT ?
• Excellent corrosion resistance in the water media of the extremely high temperature of 500℃.
• Good stress corrosion resistance
• Good machining
• High creep strength
• Very good resistance to oxidation
• Good resistance to combustion gases
• Very good resistance to carburization
• Good resistance to nitrogen absorption
• Good structural stability at high temperatures
• Good weldability
Incoloy 800/800H/800HT Application field：
• Ethylene furnace quench boilers • Hydrocarbon cracking
• Valves, fittings and other components exposed to corrosive attack from 1100-1800° F
• Industrial furnaces • Heat-treating equipment
• Chemical and petrochemical processing • Heat exchangers
• Super-heater and re-heaters in power plants • Pressure vessels
INCOLOY 800/800h /800HT alle drie hebben een zeer vergelijkbare chemische samenstelling, dus ze hebben een uitstekende weerstand tegen reductie, oxidatie, corrosie door stikstofhoudende media, evenals weerstand tegen afwisselend veranderende media corrosie door redox, en een hoge metallurgische stabiliteit in langdurige toepassingen bij hoge temperaturen.Maar door het verschil in (Al+Ti) inhoud van de drie, waardoor de omgeving waarin de drie materialen worden gebruikt verschillend is, wordt de specifieke prestatie geleverd: INCOLOY 800 komt uit bij temperaturen onder nul, bij kamertemperatuur en bij temperaturen van 600 graden celsius.INCOLOY 800H heeft een zeer goede treksterkte boven 600 graden c omdat het (Al+Ti) gehalte niet hoger is dan 0,7% en heeft nog steeds een goede taaiheid bij langdurige werkzaamheden onder 700 graden c.INCOLOY 800HT heeft een goede vloeigrens bij een temperatuur boven 700 graden celsius.
INCOLOY 800HT is in het algemeen beschikbaar als alternatief voor INCOLOY 800/800h. Het is aan te raden om regelmatig milieumaterialen te gebruiken, afhankelijk van het materiaal,
