Hastelloy B-2 yog ib qho kev daws teeb meem ntxiv dag zog rau npib tsib xee-molybdenum alloy nrog kev ua haujlwm zoo heev los txo qhov chaw xws li hydrogen hydride gas, sulfuric acid, yanoic acid, thiab phosphoric acid.Molybdenum yog lub ntsiab alloying ntsiab uas muab zoo heev corrosion kuj nyob rau hauv txo qhov chaw.Cov nickel-steel alloy no tuaj yeem siv rau hauv qhov chaw welded vim tias nws tiv thaiv kev tsim ntawm grain ciam carbide precipitates nyob rau hauv weld tshav kub-cuam tshuam cheeb tsam.
Cov npib tsib xee alloy no muab kev tiv thaiv zoo rau yan acid nyob rau hauv ntau yam ntawm cov concentrations thiab kub.Tsis tas li ntawd, Hastelloy B2 muaj kev tiv thaiv zoo heev rau pitting, kev nyuaj siab corrosion cracking, thiab riam kab thiab tshav kub cuam tshuam cheeb tsam.Alloy B2 muab kev tiv thaiv rau cov ntshiab sulfuric acid thiab ntau yam tsis-oxidizing acids.
Cov yam ntxwv ntawm Hastelloy B-2
• Zoo heev tiv thaiv kev ntxhov siab corrosion tawg thiab pitting
• Zoo kawg nkaus tiv thaiv kom txo tau cov mob xws li hydrogen chloride, sulfuric acid, acetic acid thiab phosphoric acid
• Resistant hydrochloric acid nyob rau hauv tag nrho cov concentrations thiab kub
Daim ntawv thov Hastelloy B-2:
Hastelloy B-2 yog dav siv nyob rau hauv tshuaj, petrochemical, fais fab kev lag luam thiab kev tswj cov pa phem, tshwj xeeb tshaj yog nyob rau hauv sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid thiab lwm yam lag luam.
