Sharaxa Inconel 718

Inconel 718 Codsiga

Inconel 718 wuxuu leeyahay caabbinta daxalka wanaagsan iyo iska caabinta yang ee matoorka diyaaradaha iyo codsiyada marawaxadaha gaaska. Daawaha waxaa loo isticmaalaa qaybaha u baahan iska caabbinta qulqulka badan iyo walbahaarka culeyska illaa 1300 ° F (704 ° C) iyo u adkaysiga qiiqa ilaa 1800 ° F (982 ° C). Xitaa heerkulka hoose, Mashiinka Inconel 718 wuxuu leeyahay sifudud jireed iyo saameyn saameyn leh. AMS 5662 waxay ubaahantahay xoog dhalid ≥ 150,000 psi heerkulka qolka.

Qalabka Inconel 718

Inconel 718 waxaa lagu sifeeyay inay tahay daaweyn adag oo roobab da 'ah oo da' ahaan ku adkaan karta daaweynta kuleylka. Qaab dhismeedka hadhuudhku wuxuu hayaa austenite heerkulka oo dhan. Xalal kala duwan iyo daweynta gabowga ayaa loo isticmaalaa inta lagu jiro heerkan daaweynta kuleylka si loo habeeyo sifooyinka farsamada muddada-gaaban ama muddada-dheer.
