Alloy 625 (UNS N06625)
Summary	Nickel-chromium-molybdenum alloy pamwe nekuwedzera kwe niobium inoshanda ne molybdenum kuomesa matrix yealloy uye nekudaro inopa simba rakakwirira pasina kusimbisa kupisa. Iyo alloy inopikisa huwandu hwakawanda hwenzvimbo dzinoparadza zvakanyanya uye inonyanya kushingirira kugomba uye kukoromoka. Inoshandiswa mukugadzira makemikari, aerospace uye marine engineering, kusvibisa-kudzora michina, uye nuclear reactor.

Microstructure

Alloy 625 is solid-solution matrix-yakaomeswa kumeso-centered-cubic alloy.
Vanhu

Nekuda kweiyo yakaderera katoni yemukati uye kudzikamisa kupisa kurapwa, Inconel 625 inoratidza kushoma maitiro ekukurudzira kunyangwe mushure meawa makumi mashanu patembiricha muchikamu 650 ~ 450 ℃.

Iyo alloy inopihwa mune yakapfava-yakagadziriswa mamiriro ekushandisa anosanganisira wet corrosion (Alloy 625, giredhi 1), uye inotenderwa neTUV yekumanikidza midziyo mutembiricha renji -196 kusvika 450 ℃.

Yepamusoro-tembiricha yekushandisa, pamusoro pe approx. 600 ℃, uko kunofanirwa kusimba uye kuramba kukambaira uye kuputika, mhinduro-yakawedzera vhezheni (Alloy 625, giredhi 2) ine yakakwira kabhoni yemukati inowanzo shandiswa uye inowanikwa pakukumbira mune mamwe zvigadzirwa mafomu.

Kupokana kwakasarudzika kune gomba, crevice corrosion, uye intergranular kurwisa;

Inenge rusununguko rwakakwana kubva kune chloride-induced stress-corrosion cracking;

Kuramba kwakanaka kune mineral acids, yakadai se nitric, phosphoric, sulfuric uye hydrochloric acids;

Kupikisa kwakanaka kune alkalis uye organic acids;

Zvakanaka mechanical properties.
Corrosion Resistance

Iyo yakakwira alloy yemukati yealloy 625 inoigonesa kutsungirira kwakasiyana kwakasiyana kwakakomba corrosion nharaunda. Munzvimbo dzakapfava dzakadai semhepo, mvura yakachena uye yegungwa, munyu usina kwakare, uye alkaline media panenge pasina kurwisa. Munzvimbo yekuora kwakanyanya kusanganiswa kwenickel uye chromium kunopa kuramba kune oxidizing kemikari, nepo iyo yakakwira nickel uye molybdenum zvirimo zvinopa kupikisa kune nonoxidizing kupesana nekunzwa panguva yewelding, nekudaro kudzivirira kunotevera kutsemuka kwe intergranular. Zvakare, iyo yakakwira nickel yemukati inopa kubva kune chloride ion-stress-corrosion cracking.
Applications

Iyo yakapfava-yakakwenenzverwa vhezheni yeAlloy 625 (giredhi 1) inosarudzwa kuti ishandiswe muindasitiri yemakemikari process, muinjiniya yemugungwa uye mumidziyo yekudzora kusvibiswa kwekuchengetedza nharaunda. Mashandisirwo akajairika ndeaya:

1. Superphosphoric acid kugadzira michina;

2. Midziyo yekugadziridza tsvina yenyukireya;

3. Machubhu ekugadzira gasi anovava;

4. Mapombi masisitimu uye sheathing yezvikwiriso mukutsvagisa oiri;

5. Indasitiri yeOffshore nemidziyo yemugungwa;

6. Flue gasi scrubber uye damper components;

7. Chimney linings.
Kune yakanyanya-tembiricha application, inosvika 1000 ℃, mhinduro-yakaverengerwa vhezheni yeAlloy 625 (giredhi 2) inogona kushandiswa zvinoenderana neiyo ASME kodhi yekumanikidza ngarava. Yakajairika application ndeiyi:

 

1. Zvikamu mumarara gasi system uye tsvina gasi yekuchenesa zvidyarwa zvakafumurwa kune tembiricha yepamusoro;

2. Flare stacks munzvimbo dzekunatsa uye mapuratifomu ekumahombekombe;

3. Recuperator uye compensator;

4. Submarine dhiziri injini exhaust masisitimu;

5. Superheater tubes mumarara ekupisa zvirimwa.
