What are Incoloy 800, 800H, and 800HT fasteners, and what are their key characteristics and applications?
Incoloy 800, 800H, and 800HT fasteners are high-performance alloys that belong to the Incoloy family of nickel-iron-chromium alloys. These fasteners are designed to provide exceptional corrosion resistance, strength, and high-temperature stability.
Incoloy 800 fasteners are composed of nickel, iron, and chromium, with the addition of small amounts of aluminium and titanium for improved creep and stress rupture properties. They are known for their resistance to oxidation, carburization, and nitridation, making them suitable for various applications in aggressive environments such as chemical processing, power generation, and heat-treating equipment.
Incoloy 800H fasteners have a modified chemical composition with higher carbon content, which enhances their high-temperature strength while maintaining excellent corrosion resistance. These fasteners, such as furnace components, petrochemical processing, and heat exchangers, are commonly used in applications where exposure to elevated temperatures and thermal cycling is expected.
Incoloy 800HT fasteners offer superior thermal stability due to their increased levels of aluminium and titanium. They exhibit excellent strength at elevated temperatures and are often employed in applications involving sustained high-temperature exposure, such as gas turbines, industrial furnaces, and steam generators.
How does the corrosion resistance of Incoloy 800, 800H, and 800HT fasteners compare to other materials?
Incoloy 800, 800H, and 800HT fasteners' corrosion resistance are considered excellent and highly competitive compared to other materials commonly used in fastener applications. These alloys offer exceptional resistance to various corrosive environments, including sulfuric acid, nitric acid, hydrochloric acid, and many alkaline solutions.
Compared to stainless steel, often used in various industrial applications, Incoloy 800, 800H, and 800HT fasteners demonstrate superior corrosion resistance, especially in high-temperature environments. They are less prone to stress corrosion cracking, pitting, and crevice corrosion, ensuring prolonged service life and reliability.
Incoloy 800, 800H, and 800HT fasteners exhibit similar or even better resistance to corrosive media. These alloys are particularly well-suited for environments where oxidation, carburization, and nitridation are concerns.
Manufacturing Process Of Incoloy 800 Fasteners
Forging
Forging is a manufacturing process that involves shaping metal through the application of force.
Machining & Drilling
Both machining and drilling play crucial roles in the manufacturing of components across a wide range of industries.
Heat Treatment
Heating the metal to a temperature below the critical range and then slow cooling
Quality Control & Marking, Identification
Quality control and marking are essential aspects of manufacturing and production processes across metal industries.
Packaging and Delivery
To reach their destination in pristine condition, we employ careful packaging techniques.
