I-Hastelloy Nickel Alloy B2 iyi-alloy emelana namakhemikhali enokumelana okuphezulu ekuphathweni okuphezulu nokucindezelwa ukuqhekeka endaweni eshisayo endaweni ethintekile. Ikakhulu, le alloy isebenza kahle ezindaweni ezinokhahlo njenge-sulfuric acid, hydrogen chloride ne-phosphoric acid. I-Alloy B iyaziwa nangokuthi yi-WNR 2.4617 Bolts futhi sinikeza lezi zinhlobo zama-alloys kuwo wonke amabanga abonakalayo, ama-gauges nosayizi.

Ezinye zezimpawu ze-Alloy 31 yilezi: Ukumelana kahle nokugqwala kwabezindaba ze-phosphoric acid, ukumelana kahle nokuncipha kwemithombo ye-oxychlorine yokunciphisa kanye nokubilisa ukumelana ne-67% nitric acid.

I-Alloy 926 (1.4529) Izikulufo ziyindawo efanelekile engu-316L lapho kudingeka ukumelana nokugqwala okuphezulu ngaphandle kokukhuphuka kwamandla. I-Alloy 926 Fasteners ibhekwa njenge-aloy engu-6-molybdenum (6-molybdenum noma i-6% molybdenum), efana ne-aloys al6xn al6xn kanye ne-smo 254.

I-Hastelloy B3 inokumelana kahle ne-hydrochloric acid kuyo yonke ukugxila kanye namazinga okushisa. Ngaphezu kwalokho, ithuthukisa kakhulu ukuqina kwesakhiwo ngokuqhathaniswa nama-alloys adlule we-B-Type, ukunciphisa ukukhathazeka ngesikhathi sokufudumala, ukubonwa kanye nensizakalo.

I-Alloy B (UNS N10001) yathuthukiswa ukumelana ne-hydrochloric acid. IHastelloy B2 isithathe indawo yayo. Alloy b3 (uns n10675) ukuhluka okusha ngokuqina okuphezulu okushisayo. Lezi zimbotshana ze-alloy b2 ziyi-nickel nickel molybdenum alloy engasetshenziswa esimweni se-as-welded. Imelana kakhulu ne-hydrochloric acid yazo zonke izimo zokugxila kanye namazinga okushisa. Kwaziwa njenge-UNS N10665 Bolts, lezi zimbotshana nazo zimelana nokuqhekeka kokugqwala kwengcindezelo nokukhonkotha.

I-Hastelloy B-3 iyi-nickel-molybdenum alloy enokumelana kahle nokuphamba, ukugqwala kanye nokuqhekeka kokugqwayiza kanye nokuqina okungcono kakhulu kwe-alloy b-2. Ama-hastelloy ex 100675 alungele izindiza, amakhemikhali elokufundisa, izinyosi kanye ne-turbine turbine turnition isigaba.

I-Alloy 31 inokuphikiswa okuhle kakhulu kokugqwala kwi-acidic nase-alkaline halide media; Ukumelana okuhle kakhulu ku-sulfuric acid, ngisho nokugxila okuphezulu; Ukugqwala okuhle nokuguguleka kokuphikiswa kokugqwala kwabezindaba ze-phosphoric acid. Sinikezela nge-1.4562 bolts emananini okuhola embonini.

Njengoba i-iron iyisifunda sayo esiningi kakhulu, ihlukaniswa njenge-super-autenite. Noma okuqukethwe kwe-nickel kwayo kungaphansi kwengxenye, uhlelo olungeyena luhlukanisa i-Alloy 20 njenge-alloy esekwe ku-nickel. I-Alloy 20 imelana ne-sulfuric acid eshisayo, kanti u-Alloy 20 uzinza nge-columbium ukunciphisa ukuhanjiswa kwemvula ngesikhathi se-welding. Inezakhiwo ezinhle kakhulu zemishini futhi ingakhiqizwa kalula. Yize i-alloy yenzelwe izimboni ezihlobene ne-sulfuric acid, isetshenziswa kabanzi embonini yamakhemikhali emhlabeni wonke.

Sikhiqiza ikhwalithi ephezulu ye-Alloy 20 Bolts ku-ASTM \ ASME \ ama-Din Standards kanye nemininingwane. I-Alloy 20, eyaziwa nangokuthi "Umbazi 20" kanye ne- "20CB-3", iyi-nickel-chromium-molybdenum esingenacala aklanyelwe izinhlelo zokusebenza ze-sulfuric acid. Ukumelana kwalo kokugqwala nakho kuyaziboleka kokunye ukusetshenziswa okuningi kwamakhemikhali, ukudla, amakhambi kanye nezimboni zepulasitiki. Enye yezizathu eziphambili ukuthi ama-fasteners angama-alloy ajwayelekile ukuthi amelana nokugqwala okukholweni nokukhonkotha kwe-chloride, futhi okuqukethwe yithusi kwawo akuvikela ku-sulfuric acid.

Ama-hastelloy C22 ama-fasteners angu-General-inhloso ahlanganiswe i-chromium, nickel, molybdenum ne-tungsten alloys. Le miklamo yenzelwe ukukhulisa ukumelana nokukhonkotha, ukugcwala kwengcindezelo (SSC) kanye nokuqhekeka kokugqwayiza kwe-crevice. Inokuqukethwe okuphezulu kwe-chromium kanye nokumelana okuhle ku-oxidizing media. Ukuba khona kukaMolybdenum noTungsten kunikeza ukumelana okuhle kokunciphisa imidiya. Okuqukethwe kwalo kwe-nickel kuhlinzeka ngokuphikiswa okuhle ku-oxidizing aquad media.

I-Hastelloy C-276 iyi-alloy ethandwa kakhulu kithi ngenxa yokumelana kwayo okuphezulu okuphezulu ezindaweni ezahlukahlukene.

I-Hastelloy C276 Bolts ivame ukusetshenziswa ukubamba izinto noma izinto ndawonye, ​​noma ukubeka izinto. I-fastener evame ukuba nekhanda ekugcineni eyodwa naku-chamfer kolunye. Imvamisa isetshenziswa esimweni esiphathwa solumbi futhi ifakwe ngo-1121¡Ãc (2050¡ãf) bese icishiwe.

I-Hastelloy C-2000 i-fastener, eyaziwa nangobuningi njenge-alloy C-2000, iyinhlangano eguquguqukayo ye-nickel-chromium-molybdenum alloy enokumelana kahle nokugqwala kokugqwala nokugqwala. I-C-2000 Fastener (uns N06200) ihlukile phakathi kwamanye ama-hastelloy alloys ane-1.6% yethusi engezwe ekwakhekeni kwamakhemikhali. Lezi zakhiwo zizenza zilungele izinhlelo zokusebenza ezifana nabashisi bokushisa kanye nokuphendula kwezimboni. I-Hastelloy C2000 Fasteners ihlanganisa ukumelana okuhle kakhulu ku-oxidizing media of C276 ngokumelana kahle nezimo ezingezona ze-oxidizing, okwenza kube yi-alloy eyingqayizivele yokuvikela imishini yenqubo yamakhemikhali ngaphansi kwezimo ezahlukahlukene, kufaka phakathi uketshezi olungcoliswe nge-iron ion.

I-Alloy B Ukuthandwa kwayo kuvinjelwe ukutholakala kwayo. Zonke lezi zinto zokwenziwa zilungele ukunciphisa ama-acid, kepha zilukhuni ngokulwa nama-aciding acise. Ngenxa yokuqukethwe okuphezulu kwe-molybdenum, le alloy iyabiza kakhulu kunamanye ama-alloys. Ngasikhathi sinye, inokumelana kahle nokugqwayiza okugxilwe kakhulu kwe-sulfuric acid kanye nama-acid ahlukahlukene angewona oxidizing, ukumelana kahle nokuqhekeka kwe-chloride ukuxabana kokuqhekeka (i-SCC), kanye nokumelana okuhle kuma-organi acid ahlukahlukene.

Alloy 725 (ANX N07725) yi-nickel-chromium-molybdenum-niobium alloy okuvimbela kakhulu kanye nobudala obukhuliswe kabili kumandla okushisa ama-annealed 625. Amandla we-Alloy 725 anyuswa ngokwelashwa okushisa kunokuba athole ukwelashwa okubandayo kunokuba athole ukwelashwa okubandayo kunokuba aphule ukwelashwa okubandayo kunokuba athole ukwelashwa okubandayo. Lokhu kunika namandla ezingxenyeni ezinkulu ezingalingani ezingakwazi ukuqiniswa umsebenzi obandayo. I-Alloy 725 isetshenziselwa ama-hanger, amalunga okufika kanye nama-fasteners aphezulu ezisekelweni zasolwandle.

Izinsizakusebenza ze-Alloy eziyisisekelo ze-hastelloy C276 zihlanganisa izinsimbi ezinjenge-nickel, molybdenum ne-chromium. Ngaphezu kwalezi zinsimbi ezintathu, ama-hasteloy C276 ama-fasteners nawo ane-tungsten angeziwe. Kuyaziwa ukuthi ukungezwa kwe-tungsten kuya kuma-superlloys kungathuthukisa ukumelana nokugqwala kwama-alloys ezindaweni ezahlukahlukene ezinokhahlo. I-Hastelloy C-276 Alloy inokumelana kahle nezinhlobonhlobo zenqubo yamakhemikhali, kufaka phakathi ama-oxidising agents afana nama-forric nama-chuilides, ama-a a a a a a a a acid, i-acetic anhydric, i-acetic anhydride, amanzi olwandle ne-brine.

I-Hastelloy 276 Bolts kanye ne-Fasteners zilungele izinhlelo eziningi zamakhemikhali esimweni se-welded. Kodwa-ke, kufanele kuqashelwe ukuthi ezindaweni lapho amajoyinti we-Aloy Weld atholakala khona, kufanele kubhekwe ngezinto zokuhlaselwa kwe-welld filler. I-Hastelloy C276 Socket Head Cap izikulufa futhi zinokumelana kahle nokugqwala okukhonkotha, ukugcwala kokugqwala kwengcindezelo kanye no-oxidizing atmospes kuze kube ngo-1900¡ãf.

I-Incoloy wnr 1.4876 ama-bolts anokumelana kahle nokugqwayiza okuhle futhi agweme ukwehluleka ngenxa yokugqwala komoya. Okuqukethwe okuthuthukile kwe-molybdenum okugxile ekubuzeleni ubungozi ekugqwaneni okukhonkotha. Isetshenziswa kwiphakeji equkethe i-molybdenum-equkethe i-auntenitic alloy alloy, ikhabhoni ephansi. Ngaphezu kwalokho, isetshenziselwa ukufudumala kwama-steel adinga izakhiwo ezilwa nokugqwala.

I-Hastelloy C276 Bolts isetshenziswa ezincelweni ezisindayo zomsebenzi ngenxa yekhwalithi yazo enhle yemishini. Lokhu okuqukethwe kungenye yezinto zokungamelana nokugqwala okusetshenziswa kakhulu emhlabeni. I-bolt ingasetshenziswa nge-welding ngaphandle kwemiphumela yokuvundwa kwemingcele yokusanhlamvu ngoba cishe akukho zulu ye-carbide ngesikhathi se-welding. I-Hastelloy C276 Bolts ingasetshenziswa kuzinhlelo zokusebenza zokwelashwa nge-acid ngoba impahla imelana nezimo eziningi ezilimazayo, kufaka phakathi izinhlanganisela ezisindayo ze-sulfur nama-chloride ion. Le mfanelo yenza ilungele imishini yokususela amandla, imishini yegesi ethambile nezinye izimo ezinzima.
