Hastelloy B-3 yog dab tsi?
Taw qhia ntawm Hastelloy B-3
Cov hlau no tsuas yog tsim los ntawm npib tsib xee (Ni) thiab molybdenum (Mo), nrog me me ntawm hlau (Fe), carbon (C), silicon (Si), manganese (Mn) thiab lwm yam. Qhov tseeb piv ntawm cov ntsiab lus no muab Hastelloy B-3 kev ua tau zoo heev hauv ntau qhov chaw corrosive. Tshwj xeeb, nws tuaj yeem tiv taus hydrochloric acid corrosion nyob rau hauv tag nrho ntawm qhov qis mus rau qhov kub thiab txias, nrog rau kev ua haujlwm zoo rau cov tsis-oxidizing acids xws li sulfuric acid, phosphoric acid, thiab acetic acid.
Ntxiv nrog rau nws cov kev tiv thaiv rau cov tsis-oxidizing acids, Hastelloy B-3 yog thermally ruaj khov, uas txo cov kev pheej hmoo ntawm embrittlement thaum lub sij hawm tsim khoom thiab tso cai rau nws yooj yim ua rau ntau yam duab thiab ntau thiab tsawg. Piv nrog rau nws cov thawj coj Hastelloy B-2 alloy, B-3 optimizes cov khoom ntawm cov khoom los ntawm kev kho cov tshuaj muaj pes tsawg leeg, xws li txo cov hlau thiab chromium cov ntsiab lus, tshwj xeeb tshaj yog kev txhim kho corrosion kuj ntawm kub kub.
Hais txog cov khoom siv lub cev, hastelloy b -3 muaj qhov ua kom siab thiab melting, nrog rau cov zog kho tshuab, suav nrog lub zog kho kom zoo nkauj thiab ductility. Raws li qhov kub thiab txias, txawm hais tias nws lub zog tensile yuav txo qis, nws tseem yuav nyob twj ywm ntawm qhov siab, ua kom muaj kev ntseeg siab hauv kev siv ntawm qhov kub thiab txias.
Hastelloy B-3 Kev ua tau zoo thiab kev siv
Pitting Corrosion thiab Stress Corrosion Cracking Resistance: B-3 alloy yog resistant rau pitting corrosion thiab kev nyuaj siab corrosion cracking, ua rau nws haum rau siv nyob rau hauv ib puag ncig uas xav tau cov ntaub ntawv ua tau zoo nyob rau hauv cov cheeb tsam no.
Kev tiv thaiv riam-ntug corrosion thiab tshav kub-tshuaj tiv thaiv corrosion: Lub alloy muaj peev xwm tiv taus riam-ntug corrosion thiab tshav kub-cuam tshuam cheeb tsam corrosion, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau kev siv nyob rau hauv vuam los yog high-temperature ib puag ncig.
Kev tiv thaiv rau cov tsis-oxidizing acids: Non-oxidizing acids xws li acetic acid, acetic acid, phosphoric acid, thiab lwm yam yog corrosive heev rau B-3 alloy, yog li nws yog haum rau siv nyob rau hauv kev kho mob ntawm cov tshuaj no.
Hydrochloric acid corrosion kuj: B-3 alloy muaj kev tiv thaiv zoo heev rau hydrochloric acid corrosion ntawm tag nrho cov concentrations thiab kub, uas yog ib qho ntawm cov laj thawj tseem ceeb rau nws daim ntawv thov dav.
Txhim kho kev tsim khoom: Piv rau B-2 alloy ua ntej, B-3 alloy muaj thermal stability ntau dua, uas ua rau nws yooj yim rau kev tsim khoom thiab txo qhov kev pheej hmoo ntawm embrittlement thaum ua.
Corrosion resistance: Hastelloy B-3 tuaj yeem tiv taus hydrochloric acid corrosion ntawm txhua qhov kub thiab txias, thiab tseem qhia tau hais tias zoo corrosion tsis kam rau cov xov xwm tsis-oxidizing xws li sulfuric acid, acetic acid, formic acid, thiab phosphoric acid.
Hauv cov ntsiab lus, Hastelloy B-3 tau siv dav hauv ntau qhov kev lag luam uas xav tau, xws li kev lag luam tshuaj, tshuaj thiab khoom siv tiv thaiv ib puag ncig, vim nws zoo heev corrosion kuj thiab zoo txhua yam khoom.
