Bayanin Inconel 718

Inconel 718 Aikace-aikacen

Inconel 718 yana da kyakkyawan juriya na lalata da juriya na yang a injin jet da aikace-aikacen injin turbin gas. Ana amfani da gami don sassan da ke buƙatar juriya mai ƙarfi da damuwa har zuwa 1300 ° F (704 ° C) da juriya da iskar shaka har zuwa 1800 ° F (982 ° C). Ko da a ƙananan zafin jiki, Machining Inconel 718 yana da kyawawan kaddarorin ƙarfi da tasiri. AMS 5662 yana buƙatar ƙarfin yawan amfanin ƙasa ≥ 150,000 psi a zafin jiki.

Inconel 718 injina

Inconel 718 an classified a matsayin hazo hardening gami da za a iya shekaru taurara da zafi magani. Tsarin hatsi yana kula da austenite a duk yanayin zafi. Ana amfani da hanyoyi daban-daban da kuma maganin tsufa a lokacin wannan matakin maganin zafi don inganta kayan aikin injiniya na gajeren lokaci ko na dogon lokaci.
