Inconel: Ib tsev neeg ntawm cov high-kub-ooys (feem ntau nickel-chromium raws li lawv zoo oxidation thiab corrosion tsis kam kub. Hom nquag zoo li tsis zoo li lwm tus lej 600 yog siv rau hauv cov roj av roj, kev sib pauv cua sov, thiab ua kom sov.
Incoloy 825: ib npib tsib xee-chromium-hlau alloy muaj Molybdenum thiab tooj liab. Nws txawj xav txog kev tawm tsam ntau yam ntawm cov xov xwm corrosive, suav nrog cov sulfuric acid, thiab feem ntau siv hauv kev tswj hwm tshuaj, tswj kev qias neeg.
Alloy 926: Qhov no yog ib lub siab-chromium, Nickel Alloy (25% chromium) tsim rau ob leeg corrosion thiab oxidation. Nws feem ntau siv nyob rau hauv cov ntawv thov koom nrog sulfuric acid thiab lwm yam tshuaj lom neeg.
Monel 400: lub tooj liab-nickel alloy nrog kev tiv thaiv zoo rau dej hiav txwv, acids, thiab alkalis. Nws tau siv dav hauv cov av marine, ua yeeb yam, thiab lwm cov ntawv thov uas tsis kam rau corrosion thiab yaig yog xav tau.
Hauv cov ntsiab lus, hastelloy c276 thiab inconel excel nyob rau hauv high-kub thiab morrosive ib puag ncig, thaum incoloy 825 thiab monel 400 yog qhov zoo rau cov tshuaj lom neeg tshwj xeeb. Alloy 926 muaj kev tiv thaiv zoo dua rau cov sulfuric acid thiab ib puag ncig zoo sib xws.
2. Dab tsi yog cov ntawv thov tseem ceeb ntawm cov nickel alloys hauv kev lag luam lag luam?
Teb:
Cov alloys no tau siv nyob rau hauv ntau yam kev lag luam raws lawv cov khoom tshwj xeeb. Ntawm no yog qhov twg cov khoom ci:
Hastelloy C276: feem ntau yog siv hauv kev ua qias tuaj, tswj kev ua qias tuaj, nuclear reactors, thiab flue roj desulfurization tshuab. Nws tau zoo heev rau kev tuav tshuaj txhoj puab xws li hydrochloric acid thiab sulfuric acid ntawm cov kub.
Inconel: Qhov zoo tagnrho rau cov ntawv thov kom sov xws li roj av tshuab, kev hloov pauv cua sov, cov cav dav hlau, thiab lub zog hluav taws xob. Inconel 625 thiab Inconel 718 feem ntau yog siv rau cov ntawv thov aerospace thiab nuclear vim lawv lub zog siab thiab kev tawm tsam rau huab cua sov heev.
Incoloy 825: nquag siv hauv kev siv tshuaj lom neeg thiab roj offshore, thiab kev kho mob paug rau cov acidic ib qho zoo li sulfuric thiab phosphoric acids.
Alloy 926: Zoo meej rau cov sulfuric acid ua, flue roj scrubbers, thiab cov ntawv thov marrine vim nws txoj kev tsis kam ua rau ob lub acidic thiab oxidative ib puag ncig.
Monel 400: Zoo tagnrho rau kev ua dej hiav txwv, cov twj, li qub, thiab lwm yam kev xav tau tiv thaiv dej hiav txwv, acids, thiab alkalis. Nws tau siv dav hauv Saleater ib puag ncig zoo li ntug dej drilling platform thiab nkoj.
Txhua Alleloy muaj cov nicho tshwj xeeb, xws li los ntawm kev ua haujlwm siab rau kev ua haujlwm corrosion tsis kam nyob hauv cov tub rog marine thiab tshuaj ib puag ncig.
3. Yuav ua li cas cov nickel alloys ua nyob rau hauv qhov chaw kub-ib puag ncig, thiab uas yog feem ntau cua sov-resistant?
Teb:
Cov alloys ua tau txawv nyob hauv ib puag ncig kub nyob ib puag ncig raws li lawv muaj pes tsawg leeg:
Hastelloy C276: Thaum nws yog qhov ua tau zoo allloy hauv cov chaw muaj teeb meem, nws yog feem ntau muaj rau 1000 ° F (537 ° C). Nws yog qhov zoo tagnrho rau kev tuav cov txheej txheem tshuaj kub hnyav tab sis tsis yog qhov zoo tshaj plaws rau huab cua sov.
Inconel: Paub txog nws qhov kev zam kub siab-kub lub zog, Inconel 600 thiab Inconel 625 tuaj yeem tiv taus kub txog 2200 ° F (1204 ° C). Cov alloys feem ntau siv nyob rau hauv cov roj turbines, kev hloov pauv kub, thiab lwm cov ntawv thov kub.
Incoloy 825: Thaum nws muaj qhov kev tiv thaiv qhov kub siab, nws feem ntau tau txwv rau qhov kub nyob ib ncig ntawm 1500 ° F (815 ° C). Nws tsis yog li cua sov-resistant li inconel tab sis zoo heev rau nws cov kev corrosion tsis kam.
Alloy 926: Tsim los tiv thaiv kub txog 1600 ° F (871 ° F (871 ° thiab kev txhim kho ib puag ncig yog qhov yuav tsum tau ua, xws li sulfuric acid ua.
Monel 400: Thaum nws tau zoo tsis kam mus rau corrosion, nws yog tsawg dua cov cua sov-resistant tshaj lwm cov alloys thiab feem ntau ua haujlwm tau zoo tshaj plaws txog 1000 ° F (537 ° C).
Nyob rau hauv cov nqe lus ntawm tshav kub tsis kam, inconel alloys (tshwj xeeb tshaj yog incloys 625 thiab Inconel 718) yog qhov kev xaiv ntau dua, ua rau lawv xaiv mus rau ib puag ncig kub heev.
