ALLOY B-2, UNS N10665
| Alloy B-2 UNS N10665 | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cov ntsiab lus | A corrosion-resistant solid-solution nickel-molybdenum alloy, Alloy B-2 exhibits excellent corrosion resistance in aggressive reduce media xws li hydrochloric acid nyob rau hauv ntau qhov kub thiab txias, nrog rau hauv nruab nrab-concentrated sulfuric acid txawm tias muaj cov tshuaj chloride tsawg. kev kis kab mob. Kuj tseem siv tau rau hauv acetic thiab phosphoric acids, thiab rau ntau hom organic acids. Cov hlau muaj qhov ua haujlwm zoo rau chloride-vim kev ntxhov siab corrosion tawg (SCC). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Microstructure | Alloy B-2 muaj lub ntsej muag-centered-cubic qauv. Lub alloy tswj chemistry nrog yam tsawg kawg nkaus hlau thiab chromium cov ntsiab lus txo qhov kev pheej hmoo ntawm embrittlement tshwm sim thaum fabrication, raws li qhov no retards nag lossis daus ntawm Ni4Mo theem nyob rau hauv qhov kub ntawm 700-800 ℃. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cov cim | 1. Tswj chemistry nrog tsawg kawg nkaus hlau thiab chrlmium cov ntsiab lus kom retard qhov tsim ntawm txiav txim β-theem Ni4Mo; 2. Qhov tseem ceeb corrosion kuj los txo ib puag ncig; 3. Kev tiv thaiv zoo heev rau nruab nrab-concentrated sulfuric acid thiab ib tug xov tooj ntawm non-oxidizing acids; 4. Kev tiv thaiv zoo rau chloride-induced stress-corrosion cracking (SCC); 5. Zoo tsis kam mus rau ntau yam ntawm cov organic acids. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Corrosion Resistance | Cov ntsiab lus tsis tshua muaj carbon thiab silicon ntawm Hastelloy B-2 txo cov nag lossis daus ntawm carbides thiab lwm theem nyob rau hauv thaj tsam kub-tshem ntawm welds thiab ua kom muaj kev tiv thaiv corrosion txaus txawm tias nyob rau hauv qhov xwm txheej welded. Hastelloy B-2 nthuav tawm cov tshuaj tiv thaiv zoo heev hauv kev tawm tsam kev tawm tsam xws li hydrochloric acid nyob rau hauv ntau qhov kub thiab txias, nrog rau cov tshuaj sulfuric acid hauv nruab nrab txawm tias muaj cov tshuaj chloride tsawg. Nws kuj tseem siv tau rau hauv acetic thiab phosphoric acids. Qhov zoo tshaj plaws corrosion kuj tuaj yeem tau txais tsuas yog yog tias cov khoom siv nyob rau hauv qhov tseeb metallurgical mob thiab nthuav tawm cov qauv huv. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Daim ntawv thov | Alloy B-2 yog siv nyob rau hauv ntau yam kev siv hauv kev lag luam tshuaj, tshwj xeeb tshaj yog rau cov txheej txheem uas muaj sulfuric, hydrochloric, phosphoric thiab acetic acid. B-2 tsis pom zoo siv thaum muaj ferric lossis cupric ntsev vim tias cov ntsev no yuav ua rau muaj kev xeb sai sai. Ferric lossis cupric ntsev tuaj yeem txhim kho thaum hydrochloric acid los ntawm kev sib cuag nrog hlau lossis tooj liab. |
