Product Features

GH586 is a Ni Cr Co based precipitation hardening deformation high-temperature alloy, with a temperature range of -196 ° C-800 ° C, and can be used for a short period of time at 850 ° C; Adding aluminum and titanium elements to the alloy forms a Y precipitation strengthening phase, and adding cobalt, chromium, tungsten, and molybdenum elements for solid solution strengthening; Under appropriate hot processing and heat treatment conditions, small granular carbides precipitate along the grain boundaries of alloys, playing a supplementary strengthening role; Alloys have high high-temperature strength, as well as good oxidation resistance, corrosion resistance, and erosion resistance, as well as good thermal processing and welding performance; The main products include bars, round cakes, and forged parts.

Application scope and field

This alloy is a high-performance high-temperature alloy turbine disk material independently developed by China with independent intellectual property rights. It has been used to produce heat-resistant load-bearing components for engines in aviation, aerospace and other fields, including turbine rotors for liquid oxygen/kerosene rocket engines and various types of aerospace engine turbine rotor forgings, and has been in good use.
