Peb cov neeg muag khoom tuaj yeem muab tauHastelloy B2 tubthiabHastelloy B3 tub. Tiv tauj peb kom tau txais cov ntaub ntawv ntau ntxiv thiab hais lus dawb!
Ntawm no yog cov ncauj lus kom ntxaws sib piv ntawm ob:
1. Tshuaj muaj pes tsawg leeg:
Hastelloy B2 UNS N10665:
Nickel (Ni): 65%
Molybdenum (Mo): 28-32%
Hlau (Fe): 2%
Chromium (Cr): 1%
Lwm cov ntsiab lus: me me ntawm tungsten, cobalt, manganese, silicon, carbon, sulfur, thiab phosphorus.
Hastelloy B3 UNS N10675:
Nickel (Ni): 65%
Molybdenum (Mo): 28.5%
Hlau (Fe): 1.5%
Chromium (Cr): 1%
Lwm cov ntsiab lus: me me ntawm cobalt, manganese, silicon, carbon, sulfur, thiab phosphorus.
2. Corrosion Resistance:
Ob leeg B2 thiab B3 muaj kev tiv thaiv zoo rau ntau qhov chaw corrosive, suav nrog acids, alkalis, thiab chloride-induced stress corrosion cracking (SCC).
Hastelloy Alloy B3, txawm li cas los xij, tau txhim kho kev tiv thaiv rau hydrochloric acid ntawm txhua qhov siab thiab kub piv rau B2.
3. Hastelloy b2 vs b3 inDaim ntawv thov:
Hastelloy B2 2.4617:
Feem ntau siv hauv kev ua tshuaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj sulfuric, phosphoric, hydrochloric, thiab hydrofluoric acids. Tsim nyog siv rau hauv kev txo qhov chaw.
Hastelloy B3 2.4600:
Nyiam rau daim ntawv thov uas muaj hydrochloric acid ua vim nws superior tsis kam rau cov kua qaub no. Kuj siv nyob rau hauv ib puag ncig uas muaj sulfuric, phosphoric, acetic acids, thiab lwm yam muaj zog acids. Cov txiaj ntsig tshwj xeeb hauv cov xwm txheej uas txo qis thiab oxidizing acids tam sim no ib txhij. Lub caij no, Hastelloy B3 yog qhov kev xaiv zoo dua rau qhov chaw oxidizing heev, xws li nitric thiab hydrochloric acid sib tov, vim nws muaj zog tiv thaiv pitting thiab crevice corrosion.
4. Mechanical Properties:
Ob lub alloys muaj lub zog siab thiab zoo heev fabricability. B3 feem ntau muaj cov cuab yeej kho kom zoo dua qub piv rau B2, suav nrog lub zog tensile ntau dua thiab lub zog tawm los.
5. Weldability:
2.4617 Hastelloy B2thiab2.4600 Hastelloy B3yog ob qho tib si yooj yim weldable siv cov txheej txheem welding. Txawm li cas los xij, B3 tuaj yeem muab qhov zoo dua weldability vim nws cov ntsiab lus qis dua me ntsis, uas txo qhov kev pheej hmoo ntawm kev hnov mob thiab corrosion tom ntej hauv tshav kub - thaj tsam cuam tshuam.
6. Nqi:
Tus nqi sib txawv ntawm Hastelloy B2 thiab B3 feem ntau yog tsawg, nrog kev hloov pauv nyob ntawm yam xws li kev xav tau ntawm kev lag luam thiab muaj.
Hauv cov ntsiab lus, thaum ob qho tib si Hastelloy B2 thiab B3 yog cov corrosion kuj heev - cov alloys resistant haum rau ntau hom kev siv, Hastelloy B3 muaj kev tiv thaiv zoo rau hydrochloric acid, ua rau nws muaj txiaj ntsig tshwj xeeb hauv ib puag ncig uas cov kua qaub no nthuav dav. Txawm li cas los xij, kev xaiv ntawm ob lub alloys kawg yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov thiab ib puag ncig corrosive uas lawv yuav siv.
