Incoloy Alloy 800 and 800H fasteners are widely used in high-temperature applications requiring superior oxidation and corrosion resistance. These fasteners are made of a nickel-chromium alloy with excellent strength and resistance to thermal fatigue and stress corrosion cracking. Incoloy Alloy 800 is available in many forms, including fasteners like nuts, bolts, screws, and washers. These fasteners are classified according to their size, shape, and application. The Incoloy Alloy 800 Fastener is available in various grades, such as B7, B16, and B8M, that differ in mechanical and chemical properties. The B7 grade is used mainly in high-temperature applications, while the B16 is used in low-temperature applications.
The Incoloy Alloy 800H Fastener is a variation of the Alloy 800 with higher carbon content, enhancing its strength and resistance to carburization and creep rupturing. It is commonly used in high-temperature environments, such as industrial furnaces, heat-treating facilities, chemical processing, and power generation plants. The fastener's high tensile strength and corrosion resistance make it ideal for use in harsh environments and applications that require exceptional performance.
Incoloy Alloy 800 and 800H fasteners offer many benefits, making them an excellent choice for high-temperature applications. These benefits include excellent resistance to oxidation and corrosion, high strength and durability, and superior thermal stability. Additionally, the fasteners offer exceptional resistance to carburization and stress corrosion cracking, which are prevalent in high-temperature environments.
Another benefit of Incoloy Alloy 800 and 800H fasteners is their low coefficient of thermal expansion, which ensures that they retain their shape and dimensions even at high temperatures. This feature makes them ideal for applications that require tight tolerances and precision, such as turbine engines and power generation equipment. Incoloy Alloy 800H fasteners can withstand repeated thermal cycles without losing their integrity, even under extreme stress.
Incoloy Alloy 800 and 800H fasteners are the perfect solutions for high-temperature applications requiring exceptional performance, oxidation, corrosion resistance, and thermal stability. These fasteners offer several advantages over traditional materials, including high strength and durability, excellent resistance to stress corrosion cracking, and low coefficient of thermal expansion, making them ideal for use in harsh environments.
