Alloy 625 / UNS N06625 / W.NR. 2.4856

Bayani

Alloy 625 shine nickel-chromium-molybdenum gami da ake amfani dashi don ƙarfinsa mai ƙarfi, ƙarfin ƙarfi da kyakkyawan juriya na lalata. Ƙarfin alloy 625 ya samo asali ne daga tasirin molybdenum da niobium akan matrix nickel-chromium. Ko da yake an haɓaka gami don ƙarfin zafin jiki mai ƙarfi, abun da ke tattare da shi sosai yana ba da babban matakin juriya na lalata gabaɗaya.

Masana'antu da Aikace-aikace

Ana amfani da Alloy 625 a masana'antu daban-daban, ciki har da motoci, ruwa, sararin samaniya, mai da iskar gas, sarrafa sinadarai da makaman nukiliya. Aikace-aikacen amfani na yau da kullun sun haɗa da masu musanya zafi, ƙwanƙwasa, haɗin gwiwa, tsarin shaye-shaye, masu ɗaure, kayan haɗi mai sauri da sauran aikace-aikacen da yawa waɗanda ke buƙatar ƙarfi da juriya ga mummuna yanayi.

Juriya ga Lalacewa

Alloy 625 yana da kyau juriya ga hadawan abu da iskar shaka da scaling a high yanayin zafi. A 1800ºF, juriya mai ƙima ya zama muhimmiyar mahimmanci a cikin sabis. Ya fi sauran gawawwakin zafin jiki da yawa a ƙarƙashin yanayin dumama da sanyaya cyclic. Haɗuwa da abubuwan da aka haɗa a cikin alloy 625 yana ba shi damar yin tsayayya da nau'ikan yanayi masu lalata da yawa. Kusan babu wani hari a cikin mahalli masu laushi, kamar ruwan teku sabo da ruwan teku, mahallin pH na tsaka tsaki, da kafofin watsa labarai na alkaline. Abubuwan da ke cikin chromium na wannan gami yana haifar da ingantacciyar juriya ga mahalli mai oxidizing. Babban abun ciki na molybdenum yana sanya alloy 625 mai juriya ga rami da lalata.

Kerawa da Maganin Zafi

Alloy 625 za a iya kafa ta amfani da daban-daban sanyi da zafi aiki matakai. Alloy 625 yana tsayayya da nakasawa a yanayin zafi mai zafi, saboda haka ana buƙatar manyan lodi don samar da kayan. Ya kamata a yi zafi mai zafi a cikin kewayon zafin jiki na 1700 ° zuwa 2150 ° F. A lokacin aikin sanyi, aikin kayan yana da ƙarfi da sauri fiye da na gargajiya austenitic bakin karfe. Alloy 625 yana da maganin zafi guda uku: 1) warware matsalar a 2000/2200F da iska mai kashewa ko sauri, 2) kashewa 1600/1900F da kashe iska ko sauri da 3) rage damuwa a 1100/1500 ° F da iska quenching . Magani da aka shafe (jin 2) ana amfani da shi akai-akai don aikace-aikace sama da 1500°F inda juriyar rarrafe ke da mahimmanci. Abu mai laushi (aji 1) ana amfani dashi akai-akai don ƙananan yanayin zafi kuma yana da ingantacciyar haɗuwa da kaddarorin ƙarfi da fashewa.
