Hauv kev lag luam xws li kev ua tshuaj lom neeg, kev lag luam hauv hiav txwv, thiab roj & roj, xaiv txoj cai "cov cuab yeej" tiv thaiv corrosion yog qhov tseem ceeb.Hastelloy C-22 (UNS N06022)thiabHastelloy C-276 (UNS N10276)yog ob qhov tseem ceeb tshaj plaws "Kings" ntawm nickel{0}}chromium- molybdenum alloys.
Tab sis qhov twg yog qhov zoo dua rau koj qhov project tshwj xeeb? NtawmGnee Steel, peb pab engineers thoob ntiaj teb tshawb xyuas cov kev xaiv no kom muaj kev nyab xeeb thiab kav ntev. Phau ntawv qhia no rhuav tshem txhua yam koj xav paub txog C-22 vs. C-276.
1. Chemical Composition: Sib ntaus sib tua ntawm Cr vs Mo
Thaum ob qho tib si yog Ni-Cr-Mo alloys, qhov zais cia rau lawv qhov kev ua tau zoo nyob hauv kev hloov me ntsis ntawm Chromium thiab Molybdenum.
| UNS / W. Nr | UNS / W. Nr | Ni | Cr | Mo | W | Ntsiab Feature |
| Hastelloy C-22 | N06022 / 2.4602 | Tshuav | 22% | 13% | 3% | High Chromium rau Oxidation |
| Hastelloy C-276 | N10276 / 2.4819 | Tshuav | 16% | 16% | 4% | High Molybdenum rau Kev txo qis |
C-22Muaj ntau ntau Chromium, txhim kho nws cov kev tiv thaivoxidizingib puag ncig.
C-276muaj ntau dua Molybdenum thiab tungsten cov ntsiab lus, ua rau nws superior hauvtxoib puag ncig.
2. Corrosion Resistance: Koj nyob qhov twg?
Hastelloy C-22: Tus Tswv ntawm Oxidation
Ua tsaug rau nws cov ntsiab lus chromium siab, C-22 muab kev tiv thaiv tshwj xeeb rau oxidizing aqueous media, suav nrog cov tshuaj chlorine ntub thiab cov khoom sib xyaw uas muaj nitric acid lossis oxidizing acids nrog chloride ions. Nws kuj tseem tiv taus cov vuam- tshav kub-tshem tawm tsam.
Hastelloy C-276: Tag Nrho-Rounder rau Txo
C-276 yog "tus qauv kev lag luam" vim li cas. Nws cov ntsiab lus molybdenum siab ua rau nws tsis txaus ntseeg rau pitting thiab crevice corrosion hauv kev txo cov xov xwm xws li hydrochloric acid, phosphoric acid, thiab sulfuric acid. Nws kuj ua tau zoo tshwj xeeb hauv cov pa roj qaub (H2S) ib puag ncig.
Gnee Steel Cov Lus Qhia Ua Haujlwm:Yog tias koj cov txheej txheem cuam tshuam nrog cov xwm txheej hloov pauv (ob leeg oxidizing thiab txo qis), C-22 feem ntau muaj qhov zoo dua "tag nrho" corrosion resistance, tab sis C-276 tseem yog tus nqi-zoo tshaj plaws thiab pov thawj kev daws rau feem ntau cov kev siv tshuaj.
3. Mechanical & Physical Properties
Ob lub alloys yog cov khoom ruaj khov- cov kev daws teeb meem muaj zog thiab muaj zog zoo sib xws. Txawm li cas los xij, lawv qhov ntsuas kub sib txawv me ntsis hauv kev siv lub nkoj siab:
C-22:Kev ruaj ntseg zoo heev los ntawm qhov kub thiab txias txog li 1250 ° F (677 ° C).
C-276:Feem ntau siv txog 1000℃F (538 degree) nyob rau hauv ib puag ncig corrosive.
4. Kev siv ntau & qauv
Gnee Steelmuab ob qho C-22 thiab C-276 rau kev lag luam siab:
Kev Siv Tshuaj:Reactors, tshav kub exchangers, thiab evaporators.
Pollution Control:Flue gas desulfurization (FGD) systems.
Pharmaceuticals:Cov cuab yeej siv siab -purity thiab corrosion kuj (C-22 feem ntau nyiam ntawm no).
Kev kho khib nyiab:Kev puas tsuaj pov tseg incineration thiab kev ua dej khib nyiab.
International Standards Peb ua raws li:
Seamless Yeeb Nkab:ASTM B 622 2
Phaj / Ntawv:ASTM B 575 Cov Lus Qhia Tshwj Xeeb
Bar Tshuag:ASTM B 574 Cov khoom lag luam
Forgings:ASTM B564, 1
Vim li cas koom tes nrog Gnee Steel?
Kev taw qhia qhov nyuaj ntawm npib tsib xee-raws li alloys yuav tsum muaj tus neeg xa khoom nrog qhov tob tob.Gnee Steeltsis yog ib tug distributor xwb; peb yog koj li kev koom tes hauv kev lag luam nickel alloy.
Strict Quality Control:Txhua qhov khoom xa tuaj tuaj nrog tag nrhoMTC (Material Test Certificate)raws li EN 10204 3.1, kom ntseeg tau 100% traceability.

Xaus: Kev Txiav Txim Siab
Xaiv Hastelloy C-22Yog tias koj qhov project cuam tshuam nrog cov oxidizing acids muaj zog, siab -kub oxidizing ib puag ncig, lossis yog tias koj xav tau qib siab tshaj plaws ntawm kev tiv thaiv crevice corrosion.
Xaiv Hastelloy C-276Yog tias koj tab tom cuam tshuam nrog kev txo qis acids (xws li HCl), xav tau qhov pov thawj "workhorse" nrog 50 xyoo ntawm cov ntaub ntawv, los yog xav tau tus nqi ntau dua - cov tshuaj zoo rau kev muaj zog corrosion.
