Alloy A286 Fasteners are hardware components made from a high-strength, corrosion-resistant alloy known as A286. This alloy, also referred to as Alloy 660, is a precipitation-hardening stainless steel with a unique chemical composition that includes iron, nickel, chromium, titanium, and molybdenum, among other elements. The specific chemical composition of Alloy A286 varies slightly depending on the manufacturer, but it generally includes approximately 24-27% nickel, 13.5-16% chromium, 1.3-2.2% titanium, 1-1.5% aluminum, and small amounts of molybdenum, vanadium, and other elements.
One of the key features of Alloy A286 Fasteners is their exceptional strength and high-temperature performance. These fasteners can withstand elevated temperatures, making them suitable for applications in extreme environments, such as gas turbines, jet engines, and exhaust systems. Additionally, they offer high tensile strength and excellent fatigue resistance, providing reliability and durability in demanding mechanical applications.
Corrosion resistance is another significant advantage of Alloy A286 Fasteners. The combination of chromium and nickel in the alloy provides good resistance to various corrosive media, including mildly acidic and chloride-rich environments. This makes Alloy A286 Fasteners suitable for use in aerospace, marine, and chemical processing industries, where exposure to corrosive elements is common.
