Nickel Alloy UNS N10665 Hastelloy B2

Hastelloy B2yog 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 qhov tseem ceeb ntawm cov khoom siv alloying uas muab kev tiv thaiv corrosion tseem ceeb los txo qhov chaw. Cov nickel steel alloy no tuaj yeem siv tau rau hauv qhov chaw zoo li-welded vim tias nws tiv thaiv kev tsim ntawm cov qoob loo ntawm cov ciam teb carbide precipitates nyob rau hauv qhov chaw weld tshav kub.

Corrosion Resistances

• Tag nrho corrosion, cov yam ntxwv ntawm B2 alloy tiv thaiv hydrochloric acid, sulfuric acid, phosphoric acid thiab lwm yam inorganic acids yeej ib yam li Hastelloy B alloy. Kev tiv thaiv corrosion feem ntau zoo dua li ntawm Hastelloy B alloy, tshwj xeeb tshaj yog tom qab vuam. Nyob rau hauv 20% boiling hydrochloric acid, txawm tias B2 alloy yog deformed los ntawm 50% nyob rau hauv txias ua hauj lwm, nws tsis cuam tshuam nws corrosion kuj.
• Intergranular corrosion kujVim tias cov ntsiab lus qis ntawm cov pa roj carbon, silicon thiab hlau hauv Hastelloy B2 alloy, carbides thiab qee theem intermetallic hauv sensitized steel yog tsawg dua li Hastelloy B alloy, yog li ntawd, qhov kev tiv thaiv ntawm no alloy rau intergranular corrosion zoo dua.
• Kev ntxhov siab corrosion, qhov kev ntsuam xyuas qhia tau hais tias thaum cov seem Fe Less dua los yog sib npaug rau 2% thiab Cr Less dua los yog sib npaug rau 1.0% hauv Hastelloy B2 alloy yog tsawg heev piv nrog tib alloy nrog kev tswj kom zoo ntawm cov nyiaj. ntawm hlau thiab chromium. Zoo dua qub.

Hastelloy Alloy B2 yam ntxwv

• Tswj cov hlau thiab chromium cov ntsiab lus hauv cov ntsiab lus qis, tiv thaiv kev tsim ntawm theem Ni4Mo.
• Zoo heev corrosion kuj los txo qhov ib puag ncig.
• Zoo tiv taus rau nruab nrab concentration sulfuric acid thiab ntau yam tsis-oxidizing acids.
• Kev tiv thaiv zoo heev rau chloride ion txo kev ntxhov siab corrosion cracking (SCC).
• Zoo heev tiv thaiv cov organic acid corrosion.
