What is A-286?

A-286 alloy is an iron-based deformed high-temperature alloy with excellent strength and corrosion resistance at high temperatures. Here are a few important information points about A-286 alloy:

Composition and characteristics: A-286 alloy uses Fe-25Ni-15Cr as the matrix and is comprehensively strengthened by adding molybdenum (Mo), titanium (Ti), aluminum (Al), vanadium (V) and trace amounts of boron (B). This alloy exhibits high yield strength, durability and creep strength at temperatures below 650 degrees Celsius. Processing and welding performance: A-286 not only has good mechanical properties, but also has good processing plasticity and satisfactory welding performance, making it suitable for manufacturing parts with complex shapes. Application fields: Due to its high temperature resistance, A-286 alloy is very suitable for the production of aircraft engine load-bearing parts that work under high temperature conditions for a long time, such as turbine discs, press discs, rotor blades and fasteners. In addition, the alloy can also produce deformed products of various shapes, such as discs, forgings, plates, rods, wires and rings. Production method: A-286 is usually produced by vacuum induction melting (VIM), followed by vacuum arc (VAR) or electroslag (ESR) remelting to ensure the quality and performance of the material. Heat resistance and strength: A-286 alloy maintains high strength and corrosion resistance at temperatures up to 704°C, making it an ideal material for core components in jet engines and superchargers that need to withstand extreme temperatures and pressure. Military applications: In the military field, A-286 alloy also plays an important role and is used to manufacture key components to ensure the performance and safety of equipment.
In summary, A-286 alloy has been widely used in aerospace, military and other demanding industrial fields due to its excellent high-temperature properties and ease of processing.
