NiCu 400 is a nickel-copper alloy (inenge 67% Ni - 23% Cu) inoshingirira kumvura yegungwa uye chiutsi pakupisa kwakanyanya pamwe nemunyu uye caustic mhinduro. Alloy 400 is a solid solution alloy iyo inogona kungoomeswa nekushanda kunotonhora. Iyi nickel alloy inoratidza hunhu hwakaita senge yakanaka corrosion kuramba, yakanaka weld-kugona uye yakakwirira simba. Mwero wakaderera wekuora mumvura inokurumidza kuyerera brackish kana yegungwa yakasanganiswa nekunyanya kupikisa kushushikana-kupwanya kwekuputika mumvura zhinji yakachena, uye kuramba kwayo kune akasiyana siyana ekuora kwakakonzera kushandiswa kwayo kwakakura mumashandisi emugungwa uye mamwe asiri oxidizing chloride mhinduro. Iyi nickel alloy inonyanya kupikisa hydro-chloric uye hydro-fluoric acids kana yapera simba. Sezvingatarisirwa kubva kuhuwandu hwayo hwemhangura, alloy 400 inokurumidza kurwiswa ne nitric acid uye ammonia masisitimu.
NiCu 400 ine hukuru hukuru hwemagetsi pane subzero tembiricha, inogona kushandiswa mukupisa kusvika ku1000 ° F, uye nzvimbo yayo yekunyunguduka ndeye 2370-2460 ° F. Zvisinei, Alloy 400 yakaderera musimba mumamiriro annealed saka, zvakasiyana-siyana zvehasha. inogona kushandiswa kuwedzera simba.
Hunhu hweNiCu 400
- Kudzivirira kumvura yegungwa uye kupfungaira pakupisa kukuru
- Kupokana kwakanakisa kumvura inoyerera inokurumidza brackish kana mvura yegungwa
- Kupokana kwakanakisa kudzvinyirira corrosion kupaza mumvura zhinji yakachena
- Kunyanya kurwisa hydro-chloric uye hydro-fluoric acid kana yapera simba.
- Yakanakisa kupikisa kusarerekera uye alkaline munyu uye yakakwirira kuramba kune alkalis
- Kupokana kune chloride kunokonzera kushushikana kuora kwekuputika
- Yakanaka michina zvivakwa kubva pasi-zero tembiricha kusvika 1020° F
- Inopa kumwe kuramba kune hydro-chloric uye sulfuric acid pane mwero tembiricha uye kudzika, asi kashoma zvinhu zvesarudzo kune aya acid.
Iyi alloy ine nhoroondo yakareba yekushandiswa sechinhu chinodzivirira kuora, kubva pakutanga kwezana remakore rechi20 apo yakagadziriswa sekuedza kushandisa nickel ore yakawanda yemhangura. Iyo nickel nemhangura zviri mukati meiyo ore zvaive muyero yekufungidzira iyo ikozvino yakatsanangurwa zviri pamutemo kune alloy.

Corrosion Resistant NiCu 400
NiCu Alloy 400haina kudzivirirwa kune chloride ion stress corrosion kupaza munzvimbo dzakajairwa. Kazhinji, kushorwa kwayo kwekuora kwakanaka kwazvo mukudzikisa nharaunda, asi kushata mumamiriro eoxidizing. Hazvibatsiri mu oxidizing acids, zvakadai se nitric acid uye nitrous. Zvakangodaro, inoshingirira kune akawanda alkalis, munyu, mvura, zvigadzirwa zvekudya, organic zvinhu uye mamiriro emuchadenga pakudziya kwakajairika uye kwakakwira.
Iyi nickel alloy inorwiswa mumagasi ane sulfuri pamusoro pe700 ° F uye sarufa yakanyungudutswa inorwisa alloy patembiricha inopfuura 500 ° F.
NiCu 400 inopa yakaenzana corrosion kuramba senickel asi ine yakanyanya kunyanyisa kushanda kumanikidza uye tembiricha uye nemutengo wakaderera nekuda kwekugona kwayo kugadzirwa.
Zvishandiso zveNiCu 400
- Marine engineering
- Kemikari uye hydrocarbon kugadzirisa michina
- Gasoline uye matangi emvura yakachena
- Crude petroleum stills
- De-aerating heaters
- Boiler feed water heaters nezvimwe zvinopisa zvinopisa
- Mavharuvhu, pombi, shafts, fittings, uye fasteners
- Industrial heat exchangers
- Chlorinated solvents
- Crude oil distillation towers
NiCu 400 Kugadzirwa
NiCu Alloy 400 inogona kuvezwa nyore nyore negasi-tungsten arc, gasi simbi arc kana yakadzivirirwa simbi arc maitirwo uchishandisa akakodzera simbi dzekuzadza. Iko hakuna kudikanwa kwe post weld kupisa kurapwa, zvisinei, kunyatso kuchenesa mushure mekudzikisira kwakakosha kuti optimum corrosion resistance, zvikasadaro pane njodzi yekusvibiswa uye embrittlement.
Zvigadzirwa zvakapedzwa zvinogona kubudiswa kune zvakasiyana-siyana zvemakina kana kutonga kwakakodzera kwehuwandu hwekushanda kunopisa kana kutonhora uye kusarudzwa kwehutano hwakakodzera hwekupisa hunoitwa.
Kufanana nemamwe akawanda nickel alloys, NiCu 400 inowanzoomesera muchina uye inoshanda zvakaomarara. Nekudaro, mhedzisiro yakanaka inogona kuwanikwa kana iwe ukaita sarudzo dzakaringana dzekushandisa uye machining.
