INCONEL 718, Ingxubevange 718

I-N07718 tubing, i-Alloy 718 amapuleti, Inconel 718 imigoqo eyindilinga

I-INCONEL alloy 718 (UNS N07718/W.Nr. 2.4668) iwumthombo we-nickel chromium onamandla, ongagqwali osetshenziswa ku -423° ukuya ku-1300°F. Imikhawulo yokuqamba evamile iboniswa kuThebula elingezansi.

I-alloy eqinile ngeminyaka ingenziwa kalula, ngisho nezingxenye eziyinkimbinkimbi. Izici zayo zokushisela, ikakhulukazi ukumelana kwayo nokuqhekeka kwe-weld, okuvelele.

Ukunethezeka nomnotho okungenziwa ngawo i-INCONEL alloy 718, kuhlanganiswe nokushuba okuhle, ukukhathala, ukukhasa, namandla okuphuka, kubangele ukusetshenziswa kwayo ezinhlobonhlobo zezinhlelo zokusebenza. Izibonelo zalokhu izingxenye zamarokhethi aphehlwa uketshezi, izindandatho, amakesi, izingxenye zensimbi ezakhiwe ezihlukahlukene zezindiza nezinjini zegesi esebenza emhlabeni, kanye ne-cryogenic tankage. Ibuye isetshenziselwe izinsimbi kanye nezingxenye zezinsimbi.

Izicelo

I-Inconel 718 isetshenziswa ezinhlelweni ezidinga amandla aphezulu njengezingxenye ze-turbine yegesi kanye namathangi okugcina ama-cryogenic. Izinjini zejethi, imizimba yephampu nezingxenye, ama-rocket motor nama-thrust reverser, ama-spacers ento kaphethiloli enuzi, amathuluzi okukhipha ashisayo. Okunye ukusetshenziswa okudumile ukubopha okunamandla aphezulu, kanye ne-downhole shafting.

I-LKALLOY ingumphakeli oholayo we-Inconel Alloy 718 namanye ama-alloys ensimbi akhethekile angamashumi eminyaka esipiliyoni kanye nokucaciswa okubanzi. Ukuthenga noma ukufunda okwengeziwe nge-Alloy 718, xhumana nathi manje.
