Ingxubevange 625 (UNS N06625)
Isishwankathelo	I-nickel-chromium-molybdenum alloy kunye nokongezwa kwe-niobium esebenza kunye ne-molybdenum ukuqinisa i-matrix ye-alloy kwaye ngaloo ndlela inikeze amandla aphezulu ngaphandle kokuqinisa unyango lobushushu. I-alloy imelana noluhlu olubanzi lwemekobume ezonakalisa kakhulu kwaye ixhathisa ngokukodwa kwimingxuma kunye nokuhlwa kwemingxuma. Isetyenziswa ekusetyenzweni kweekhemikhali, kwi-aerospace kunye nobunjineli baselwandle, izixhobo zokulawula ungcoliseko, kunye nezixhobo zenyukliya.

Microstructure

I-alloy 625 yi-solution-solution matrix-iqinile ubuso-centered-cubic alloy.
Abalinganiswa

Ngenxa yomxholo wekhathoni ephantsi kunye nokuzinzisa unyango lobushushu, i-Inconel 625 ibonisa ukuthambekela okuncinci kwi-sensitization nasemva kweyure ye-50 kumaqondo obushushu kuluhlu lwe-650 ~ 450 ℃.

I-alloy inikezelwa kwimeko ethambileyo yezicelo ezibandakanya ukubola okumanzi (i-Alloy 625, ibakala 1), kwaye ivunyiwe yi-TUV yemikhumbi yoxinzelelo kwiqondo lokushisa -196 ukuya kwi-450 ℃.

Kwizicelo zobushushu obuphezulu, ngaphezulu kwe-approx. 600℃, apho amandla aphezulu kunye nokumelana nokurhubuluza kunye nokugqabhuka kufuneka, uguqulelo lwesisombululo (Ingxubevange 625, ibakala lesi-2) olunomxholo ophezulu wekhabhoni luqhele ukuqashwa kwaye lufumaneke xa luceliwe kwezinye iifom zeemveliso.

Ukuchasana okugqwesileyo kwi-pitting, ukubola, kunye nokuhlaselwa kwe-intergranular;

Phantse inkululeko epheleleyo kwi-chloride-induced stress-corrosion cracking;

Ukuchasana kakuhle kwi-acids yamaminerali, njenge-nitric, i-phosphoric, i-sulfuric kunye ne-hydrochloric acids;

Ukumelana kakuhle ne-alkali kunye ne-organic acids;

Iimpawu ezilungileyo zoomatshini.
Ukunyangwa kokuMhlwa

Umxholo we-alloy ophezulu we-alloy 625 uvumela ukuba imelane neentlobo ezininzi zokusingqongileyo ezinobungozi. Kwiindawo ezithambileyo ezifana nomoya, amanzi amatsha kunye nolwandle, iityuwa ezingathathi hlangothi, kunye nemidiya ye-alkaline phantse akukho kuhlaselwa. Kwimeko-bume eyingozi kakhulu ye-corrosion indibaniselwano ye-nickel kunye ne-chromium inika ukuxhathisa kwimichiza ye-oxidizing, ngelixa i-nickel ephezulu kunye nemixholo ye-molybdenum inikezela ukuxhathisa i-nonoxidizing ngokuchasene nokuvuselela ngexesha le-welding, ngaloo ndlela ithintela ukuqhekeka okulandelayo kwe-intergranular. Kwakhona, umxholo ophezulu we-nickel unikezela kwi-chloride ion-stress-corrosion cracking.
Usetyenziso

I-soft-annealed version ye-Alloy 625 (ibakala 1) ikhethwa kwizicelo kwishishini lenkqubo yeekhemikhali, kubunjineli baselwandle nakwizixhobo zokulawula ukungcoliseka kwendalo. Usetyenziso oluqhelekileyo lu:

1. Izixhobo zokuvelisa i-asidi ye-superphosphoric;

2. Isixhobo sokulungisa kwakhona inkunkuma yenyukliya;

3. Imibhobho yokuvelisa igesi emuncu;

4. Iinkqubo zemibhobho kunye nokukhukuliswa kwezixhobo zokunyuka kwi-oyile;

5. Umzi-mveliso we-offshore kunye nezixhobo zaselwandle;

6. I-flue gas scrubber kunye nezixhobo zokudambisa;

7. Iintsimbi zetshimini.
Ukusetyenziswa kobushushu obuphezulu, ukuya kuthi ga kwi-1000 ℃, isisombululo-i-annealed version ye-Alloy 625 (ibakala lesi-2) ingasetyenziselwa ngokuhambelana nekhowudi ye-ASME yemikhumbi yoxinzelelo. Usetyenziso oluqhelekileyo zezi:

 

1. Amacandelo kwinkqubo yegesi emdaka kunye nezixhobo zokucoca igesi emdaka ezivezwe kumaqondo obushushu aphezulu;

2. Iimfumba ezivuthayo kwiindawo zokucokisa kunye namaqonga angaphesheya konxweme;

3. Umxhasi kunye nababuyekezi;

4. Iinkqubo zokukhupha injini yedizili kwinkwili;

5. Iityhubhu ze-Superheater kwizityalo zokutshisa inkunkuma.
