Aerospace Incoloy 20 fasteners
Aerospace Incoloy 20 fasteners are made from a high-performance nickel-chromium-molybdenum-copper alloy. They are designed for extreme corrosive environments and high-temperature, high-pressure conditions. The addition of copper and niobium in the alloy greatly improves the resistance to acid corrosion. These fasteners also have excellent mechanical strength and long-term stability.
Aerospace Incoloy 20 fasteners are widely used in aerospace (engines, fuel systems), chemical (reactors, piping), and energy sectors (offshore platforms, nuclear power). Their corrosion resistance, high-temperature tolerance, and high strength can handle acid corrosion, salt spray, and radiation environments. This greatly increases the reliability and service life of key components in extreme conditions.
Features of Aerospace Incoloy 20 fasteners
Excellent corrosion resistance: Aerospace Incoloy 20 fasteners have strong resistance to sulfuric acid, phosphoric acid, and chloride stress corrosion cracking (SCC). They are suitable for acidic media and marine environments.
Stable high-temperature performance: Aerospace Incoloy 20 fasteners maintain high strength between -200°C and +600°C. Their oxidation resistance is better than that of ordinary stainless steel.
High mechanical strength: Aerospace Incoloy 20 fasteners are processed by cold working and age hardening. Their tensile strength can reach over 800 MPa. This meets the requirements for aviation dynamic loads.
Precision manufacturing: Aerospace Incoloy 20 fasteners are made with CNC turning and thread rolling technology. Their dimensional tolerances meet ISO Grade 1 standards. They are suitable for high-precision assembly.
Applications of Aerospace Incoloy 20 fasteners
Aerospace: Aerospace Incoloy 20 fasteners are used for engine compartment bolts and fuel system fasteners. They can withstand corrosion from aviation fuel and high-temperature exhaust gases.
Chemical equipment: Aerospace Incoloy 20 fasteners replace 316L stainless steel in reactors and pipe flanges. They extend the service life of equipment in strong acid environments.
Energy sector: Aerospace Incoloy 20 fasteners are used in offshore platform drilling equipment and nuclear power valves. They solve material degradation problems in salt spray and radiation environments.
