Hastelloy B-2 / B-3 Chaw tsim tshuaj paus
Cov npe lag luam: Hastelloy B-2,NS3202,UNS N10665,NiMo28,W.Nr.2.467,NiMo28
Hastelloy B2 yog ib qho kev daws teeb meem ntxiv dag zog, npib tsib xee-molybdenum alloy, nrog kev tiv thaiv tseem ceeb los txo qhov chaw xws li hydrogen chloride gas, thiab sulfuric, acetic thiab phosphoric acids.Molybdenum yog lub ntsiab alloying uas muab kev tiv thaiv corrosion tseem ceeb los txo qhov chaw.Cov nickel hlau alloy no tuaj yeem siv tau rau hauv qhov chaw zoo li-welded vim tias nws tiv thaiv kev tsim cov qoob loo ntawm cov ciam teb carbide precipitates nyob rau hauv qhov chaw weld tshav kub.Cov nickel alloy no muab kev tiv thaiv zoo rau hydrochloric acid ntawm txhua qhov ntau thiab kub.Tsis tas li ntawd, Hastelloy B2 muaj kev tiv thaiv zoo heev rau pitting, kev nyuaj siab corrosion cracking thiab rau riam-kab thiab tshav kub-tshem tawm tsam.Alloy B2 muab kev tiv thaiv rau cov ntshiab sulfuric acid thiab ib tug xov tooj ntawm non-oxidizing acids.

Vim li cas Hastelloy B-2?
Alloy B-2 muaj kev tiv thaiv tsis zoo rau oxidizingenvironments, yog li ntawd, nws tsis pom zoo siv rau hauv oxidizing media los yog nyob rau hauv lub xub ntiag ntawm ferric los yog cupric ntsev, vim hais tias lawv yuav ua rau sai sai corrosion tsis ua hauj lwm.Cov ntsev no tuaj yeem txhim kho thaum hydrochloric acid los ntawm kev sib cuag nrog hlau thiab tooj liab.Yog li ntawd, yog tias cov hlau no siv nrog cov hlau los yog tooj liab kav hauv ib lub cev uas muaj hydrochloric acid, qhov muaj cov ntsev no tuaj yeem ua rau cov hlau tsis ua haujlwm ntxov.Tsis tas li ntawd, cov nickel hlau alloy no yuav tsum tsis txhob siv ntawm qhov kub ntawm 1000 ° F thiab 1600 ° F vim tias qhov txo qis hauv cov ductility hauv cov hlau.
•Zoo heev corrosion kuj rau reductive ib puag ncig.
•Kev tiv thaiv zoo heev rau sulfuric acid (tshwj tsis yog cov concentrated) thiab lwm yam tsis-oxidizing acids.
•Kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg (SCC) tshwm sim los ntawm chlorides.
•Zoo heev tiv thaiv corrosion los ntawm cov organic acids.
•Zoo corrosion kuj txawm rau vuam kub cuam tshuam cheeb tsam vim tsis tshua muaj concentration ntawm carbon thiab silicon.
Hastelloy B-2 Daim ntawv thov teb:
Dav siv nyob rau hauv cov tshuaj, petrochemical, lub zog tsim thiab kev tswj cov pa phem cuam tshuam txog kev ua thiab cov cuab yeej siv,
tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem cuam tshuam nrog ntau cov kua qaub (sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid,
thiab lwm yam
