Nimonic 90 Bolts

90 Nimonic Bolts are composed primarily of nickel, chromium, and cobalt. The chemical composition is often referred to as a superalloy, meaning it is designed with properties that can withstand severe heat and corrosion. In addition to the primary components, there can also be traces of titanium, carbon, molybdenum, aluminium, silicon and iron. The high percentage of nickel creates a robust metallic bond within the piece. Nimonic 90 Bolts have been used in aircraft engines, valves, and other industrial gas turbine applications due to their challenging metal composition and resistance to heat fatigue crack growth.

Nimonic 90 Bolts have a wide range of applications. These nickel-base alloy bolts are lightweight, malleable, and corrosion resistant with high strength and the ability to handle extremely high temperatures beyond 1000° C. Nimonic 90 Bolts are highly desirable for aerospace industry applications, particularly for jet engines, where their heat and corrosion resistance is highly advantageous. They offer good fatigue properties at elevated temperatures due to higher creep strength and increased operating temperature ranges, making them ideal for other applications, such as exhaust systems requiring higher tensile strengths or creep-resistant fasteners. Their low thermal expansion rate also allows for better assembly line accuracy than conventional screws and bolts when manufacturing welded components.
