In high-temperature and corrosive industrial environments, material performance directly affects equipment safety, service life, and operating costs. Incoloy 800 Alloy, a nickel-iron-chromium alloy, has become a preferred material for industries requiring excellent heat resistance, oxidation resistance, and long-term structural stability.
In this guide, we will explain what Incoloy 800 is, where it is used, and how to select a reliable Incoloy 800 supplier for your project.
What Is Incoloy 800?
Incoloy 800 alloy is a Ni-Fe-Cr alloy designed for use in environments exposed to high temperatures and aggressive atmospheres. Unlike many stainless steels, Incoloy 800 maintains excellent mechanical strength and microstructural stability at temperatures up to 800°C (1470°F).
Key characteristics include:
High resistance to oxidation and carburization
Excellent creep and rupture strength
Good resistance to chloride stress corrosion cracking
Stable performance during long-term thermal exposure
Because of these properties, Incoloy 800 is widely used in petrochemical, energy, and furnace engineering sectors.

Chemical Composition and Mechanical Properties Overview
Incoloy alloy 800 typically contains:
Nickel (30–35%)
Chromium (19–23%)
Iron (balance)
Controlled aluminum and titanium additions
This balanced composition allows Incoloy 800 to form a stable oxide layer at high temperatures while maintaining internal structural strength.
Compared with conventional heat-resistant stainless steels, Incoloy 800 offers longer service life and lower maintenance frequency, especially in continuous-operation systems.
Typical Applications of Incoloy 800
Incoloy 800 is commonly used in applications where both thermal stability and corrosion resistance are critical:
1. Petrochemical & Refining Industry
Ethylene cracking furnace tubes
Heat exchanger tubing
Reformer components
2. Power Generation
Superheater and reheater tubing
Nuclear steam generator components
High-temperature piping systems
3. Industrial Furnaces
Furnace muffles and retorts
Heat treatment fixtures
Burner components
4. Chemical Processing Equipment
Acid-resistant vessels
High-temperature reaction pipes
Process heaters
These applications often require materials supplied under ASTM, ASME, EN, or DIN standards, which professional suppliers should fully support.
Incoloy 800 vs Incoloy 800H vs 800HT
Although closely related, these grades are not interchangeable in all applications.
Incoloy 800: General-purpose grade for heat exchangers and industrial equipment
Incoloy 800H: Higher carbon content for pressure vessels and elevated-temperature strength
Incoloy 800HT: Tighter Al + Ti control for long-term high-temperature exposure
⚠️ Choosing the wrong grade may lead to premature failure or non-compliance with pressure equipment regulations.

About Incoloy 800 Alloy
What is Incoloy 800 mainly used for?
Incoloy 800 alloy is primarily used in high-temperature and corrosion-resistant environments, especially where long-term thermal stability is required. Typical applications include heat exchangers, petrochemical furnaces, power plant boiler components, and chemical processing equipment.
Because of its excellent resistance to oxidation and carburization, Incoloy 800 is often selected over conventional stainless steels for continuous high-temperature service.
👉 For detailed product forms and specifications, please refer to our Incoloy 800 product page.
What temperature can Incoloy Alloy 800 withstand?
Incoloy 800 alloy can generally operate at temperatures up to 800–900°C under continuous service conditions, depending on stress level and environment. For applications involving higher creep resistance or pressure equipment, grades such as Incoloy 800H or 800HT may be more suitable.
Selecting the correct grade is critical for safety and service life.
What is the difference between Incoloy 800 and stainless steel?
Compared with common stainless steels, Incoloy 800 offers:
Better high-temperature strength
Superior resistance to oxidation and carburization
Improved long-term structural stability
While stainless steel is cost-effective for moderate conditions, Incoloy Alloy 800 is preferred for severe thermal and chemical environments where equipment failure is not an option.
Is Incoloy 800 easy to fabricate and weld?
Yes. Incoloy Alloy 800 has good weldability and formability, provided that standard nickel alloy processing techniques are followed. It can be welded using common welding methods such as TIG welding, MIG welding, and SMAW welding.
For thick sections or critical applications, pre- and post-weld heat treatments are recommended to optimize performance.
What product forms of Incoloy 800 are commonly available?
A reliable supplier should be able to provide Incoloy Alloy 800 in multiple forms, including:
Plates and sheets
Pipes and tubes (seamless or welded)
Bars and rods
Narrow strips and precision slit coils
Wires and wire rods
Having multiple forms available from one supplier helps reduce procurement complexity and lead time.
How do I choose a reliable Incoloy 800 supplier?
When selecting an Incoloy Alloy 800 supplier, consider the following:
Compliance with ASTM, ASME, EN, or DIN standards
Availability of Mill Test Certificates (EN 10204 3.1)
Stable inventory and processing capability
Experience with global export and industrial projects
Working with an experienced supplier ensures material consistency, technical support, and reliable delivery.

Is Incoloy 800 suitable for pressure vessels?
Incoloy 800 can be used in certain pressure vessel applications; however, Incoloy 800H or 800HT is more commonly specified due to their enhanced creep rupture strength and controlled grain size.
Always confirm the applicable code requirements (ASME, PED, etc.) before material selection.
