Incoloy 800H Alloy Bar N08810, Incoloy 800HT for High-Temperature and Oxidation Resistance

The Incoloy 800H Alloy Bar N08810 and Incoloy 800HT are high - performance nickel - iron - chromium alloys specifically engineered to excel in high - temperature and oxidation - prone environments. These alloy bars are part of our comprehensive range of nickel - based precision alloys, which are manufactured by a leading global manufacturer with a rich history of innovation and quality in the special steel industry.

• Elemental Makeup: Incoloy 800H and 800HT have a well - balanced chemical composition. They typically contain around 30 - 35% nickel, 19 - 23% chromium, and the remainder is mainly iron, along with small amounts of other elements such as carbon, silicon, manganese, and titanium. This specific combination of elements gives the alloy its unique properties.

• Microstructure: The alloys possess a stable austenitic microstructure, which is crucial for maintaining their mechanical properties at elevated temperatures. This microstructure also contributes to their excellent resistance to thermal fatigue and creep.

• Thermal Stability: These alloy bars can withstand extremely high temperatures without significant loss of strength or deformation. Incoloy 800H and 800HT are suitable for applications where the temperature can reach up to 1100°C (2012°F). Their high - temperature strength is a result of the precipitation of fine carbides and intermetallic compounds within the austenitic matrix, which pin dislocations and prevent grain growth.

• Creep Resistance: Creep is the slow, time - dependent deformation of a material under a constant load at high temperatures. Incoloy 800H and 800HT exhibit excellent creep resistance, making them ideal for long - term use in high - temperature applications such as furnace components, heat exchangers, and power generation equipment.

• Passive Oxide Layer: When exposed to high - temperature oxidizing environments, Incoloy 800H and 800HT form a dense, adherent chromium - rich oxide layer on their surface. This passive oxide layer acts as a barrier, preventing further oxidation of the underlying metal and protecting the alloy from corrosion.

• Resistance to Carburization and Nitridation: In addition to oxidation resistance, these alloys also show good resistance to carburization (the absorption of carbon) and nitridation (the absorption of nitrogen) in high - temperature environments. This makes them suitable for use in chemical processing plants, petrochemical refineries, and other industries where exposure to carbon - and nitrogen - containing gases is common.

• Polishing: The alloy bars undergo a polishing surface treatment, which not only gives them an aesthetically pleasing silver appearance but also enhances their corrosion resistance. The smooth surface reduces the number of sites where corrosion can initiate and makes the bars easier to clean and maintain.

• Customization: We offer the option to customize the shape of the alloy bars according to your specific blueprint requirements. Whether you need a simple cylindrical bar or a complex, custom - shaped component, our advanced manufacturing capabilities allow us to meet your exact specifications.

• International Standards: Our Incoloy 800H Alloy Bar N08810 and Incoloy 800HT are manufactured in strict accordance with international standards such as ASTM, EN, and JIS. This ensures that the products meet the highest quality and performance requirements in the global market.

• Testing and Inspection: Each batch of alloy bars undergoes rigorous testing and inspection procedures. We use advanced non - destructive testing (NDT) methods such as ultrasonic testing (UT) and magnetic particle testing (MT) to detect any internal or surface defects. Our NDT services are certified by SGS and BV, ensuring the reliability and safety of our products.

• Industrial Furnaces: The high - temperature and oxidation resistance of Incoloy 800H and 800HT make them ideal for use in industrial furnace components such as heating elements, radiant tubes, and furnace linings.

• Chemical Processing: In the chemical processing industry, these alloy bars are used in reactors, heat exchangers, and piping systems where they are exposed to high - temperature and corrosive chemicals.

• Power Generation: In power generation plants, Incoloy 800H and 800HT are used in boiler tubes, superheaters, and other components that operate at high temperatures and pressures.

• Aerospace and Defense: The excellent mechanical properties and high - temperature performance of these alloys also make them suitable for aerospace and defense applications, such as turbine engine components and missile parts.

In conclusion, the Incoloy 800H Alloy Bar N08810 and Incoloy 800HT are reliable and high - performance solutions for applications that require high - temperature and oxidation resistance. With our commitment to quality, customization, and compliance with international standards, we are confident that these alloy bars will meet your specific needs and exceed your expectations.
