Aikace-aikace
Alloy 825 shine austenitic nickel-iron-chromium gami kuma an bayyana shi ta hanyar kari na molybdenum, jan karfe da titanium. An haɓaka shi don ba da juriya na musamman ga wurare masu lalata da yawa, duka biyun oxidizing da ragewa.
Alloy 825 an haɓaka shi don samar da juriya na musamman ga mahalli masu yawa masu lalata, duka oxidizing da ragewa. Tare da kewayon abun ciki na nickel tsakanin 38%-46%, wannan matakin yana nuna juriya ga lalata lalata (SCC) wanda chlorides da alkalis suka jawo. Abubuwan da ke cikin nickel sun wadatar don jure jurewar chloride-ion stress-corrosion crack. Nickel, tare da haɗin gwiwar molybdenum da jan karfe, yana ba da juriya mai ban mamaki don rage yanayi kamar waɗanda ke ɗauke da sulfuric da phosphoric acid.
Abubuwan da ke cikin chromium da molybdenum kuma suna ba da juriya mai kyau a duk mahalli ban da maganin chloride mai ƙarfi mai ƙarfi. An yi amfani da shi azaman kayan aiki mai tasiri a cikin yanayi iri-iri na tsari, gami 825 yana kula da kyawawan kaddarorin inji daga yanayin zafi na cryogenic har zuwa 1,000 ° F.
Bugu da ƙari na titanium yana tabbatar da Alloy 825 akan hankali a cikin yanayin welded yana sa gami da juriya ga harin intergranular bayan bayyanar yanayin zafi a cikin kewayon da zai wayar da kan bakin karfe mara kyau. Ƙirƙirar Alloy 825 shine nau'i na nau'i na nickel-base alloys, tare da kayan da ake iya tsarawa da kuma walƙiya ta hanyoyi daban-daban.
Wannan abu yana da kyakkyawan tsari, na hali na nickel-base alloys, yana barin kayan da za a lankwasa su zuwa ƙananan radii. Annealing bayan lankwasawa ba ya zama dole.
Yana kama da alloy 800 amma ya inganta juriya ga lalata mai ruwa. Yana da kyakkyawan juriya ga duka ragewa da oxidizing acid, zuwa lalata-lalata, da kai hari a cikin gida kamar lalatawar rami da ɓarna. Alloy 825 yana da tsayayya musamman ga sulfuric da phosphoric acid. Ana amfani da wannan gawa na nickel don sarrafa sinadarai, kayan sarrafa gurɓatawa, bututun mai da iskar gas, sake sarrafa mai na nukiliya, samar da acid, da kayan tsinke.
