INCOLOY 825 (UNS N08825 / NS142)

Alloy 825 wani ƙarfe ne na nickel-iron-chromium wanda aka ƙara shi ta hanyar ƙara molybdenum, jan ƙarfe da titanium. An ƙera shi don samar da juriya ta musamman ga mahalli masu yawa na lalata, duka na oxidizing da ragewa.

An ƙera Alloy 825 don samar da juriya ta musamman ga wurare da yawa masu lalata, duka na oxidizing da ragewa. Tare da yawan sinadarin nickel tsakanin 38%–46%, wannan matakin yana nuna juriya mai ƙarfi ga tsatsagewar lalata (SCC) wanda chlorides da alkalis ke haifarwa. Yawan sinadarin nickel ya isa ga juriya ga tsatsagewar chloride-ion stress-corrosion. Nickel, tare da molybdenum da jan ƙarfe, yana kuma ba da juriya mai kyau ga mahalli masu ragewa kamar waɗanda ke ɗauke da acid sulfuric da phosphoric.

Abubuwan da ke cikin chromium da molybdenum suma suna ba da kyakkyawan juriya ga ramuka a duk muhalli banda magungunan chloride masu ƙarfi. Ana amfani da su azaman kayan aiki mai tasiri a cikin nau'ikan yanayin aiki iri-iri, gami 825 yana kiyaye kyawawan halayen injiniya daga yanayin zafi mai sanyi har zuwa 1,000° F.

Ƙara titanium yana daidaita Alloy 825 daga jijjigawa a cikin yanayin da aka haɗa, wanda hakan ke sa ƙarfen ya jure wa harin da ke tsakanin granular bayan ya shagaltu da yanayin zafi a cikin kewayon da zai sa ƙarfen bakin ƙarfe mara ƙarfi ya jijjiga. Ƙirƙirar Alloy 825 abu ne da aka saba da ƙarfen nickel, tare da kayan da ake iya ƙirƙirawa cikin sauƙi kuma ana iya haɗa su ta hanyoyi daban-daban.

Wannan kayan yana da kyakkyawan tsari, wanda aka saba amfani da shi a cikin ƙarfe mai tushe na nickel, wanda ke ba da damar lanƙwasa kayan zuwa ƙananan radiyo. Ba a buƙatar a shafa bayan lanƙwasa ba.

Yana kama da alloy 800 amma yana da ingantaccen juriya ga tsatsa mai ruwa. Yana da kyakkyawan juriya ga ragewa da kuma tsatsa mai guba, ga tsatsa mai damuwa, da kuma hare-haren da ake kaiwa a wasu wurare kamar su lalata bututu da kuma tsatsa mai rauni. Alloy 825 yana da juriya musamman ga acid sulfuric da phosphoric. Ana amfani da wannan gami na ƙarfe nickel don sarrafa sinadarai, kayan aikin sarrafa gurɓatawa, bututun mai da iskar gas, sake sarrafa man nukiliya, samar da acid, da kayan aikin tsinkewa.
