Incoloy A-286 Overview

Incoloy A-286 is a Fe-25Ni-15Cr-based high-temperature alloy, which is comprehensively strengthened by adding platinum, aluminum, vanadium and trace amounts of boron. It has high yield strength, durability and creep strength below 650°C, and has good processing plasticity and satisfactory welding performance. It is suitable for manufacturing high-temperature load-bearing parts of aeroengines that operate below 650°C for a long time, such as turbine discs, press discs, rotor blades and fasteners, etc. This alloy can produce deformed products of various shapes, such as discs, forgings, plates, rods, wires and ring parts, etc.

High-quality Incoloy A-286 alloy is developed on the basis of Incoloy A-286 alloy. As long as the purity of the alloy is improved, the gas content is limited, the content of low melting point elements is controlled, and the heat treatment system is adjusted, the thermal strength of the alloy and Improved performance over long term use.
