Poudres métalliques sphériques GH4099 Poudre d'alliage haute température à base de nickel

Caractère du produit GH4099 is a typical aging strengthened nickel based high-temperature alloy, which is comprehensively strengthened with elements such as Co, W, Al, Ti, etc., giving the alloy high thermal strength. It can be used for a long time below 900 ℃, and the highest working temperature can reach 1000 ℃. Due to its stable microstructure and satisfactory cold and hot forming and welding process performance, GH4099 high-temperature alloy is very suitable for manufacturing high-temperature plate load-bearing welding structures such as aviation engine combustion chambers and afterburner chambers.   2. cahier des charges GH4099 powder
