👉 Inconel yog zoo dua rau huab cua kub

3. Corrosion Resistance

👉 Hastelloy yog qhov zoo tshaj plaws nyob rau hauv ib puag ncig tshuaj

4. Mechanical Strength

Inconel (tshwj xeeb tshaj yog 718) muajsiab zog tensile thiab creep kuj

Hastelloy tsom ntau raucorrosion kuj tshaj lub zog

5. Tus nqi sib piv

Hastelloy feem ntau yogkim duavim muaj molybdenum ntau dua

Inconel muab tau zoo duatus nqi -kev ua tau zoo piv rau hauv siab - siv kub

Ntev - lub sijhawm ua haujlwm ruaj khov

👉 Qhov zoo tshaj plaws xaiv:Inconel

🔧 Xaiv Inconel yog:

Kub kub> 800 degree

Thermal qaug zog yog qhov tseem ceeb

Oxidation kuj yuav tsum tau

Aerospace / turbine daim ntawv thov

🧪 Xaiv Hastelloy yog tias:

Muaj zog acid ib puag ncig

Chemical processing system

High chloride corrosion

Ntev - lub sij hawm corrosion kuj yuav tsum tau

Qhov twg zoo dua, Inconel lossis Hastelloy?

Nws nyob ntawm daim ntawv thov. Inconel zoo dua rau siab - qhov kub thiab txias ib puag ncig, thaum Hastelloy zoo dua rau cov tshuaj muaj zog corrosion kuj.

Puas yog Hastelloy tiv taus corrosion ntau dua li Inconel?

Yog, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig xws li sulfuric los yog hydrochloric acid.

Puas yog Inconel muaj zog dua Hastelloy?

Feem ntau yog, tshwj xeeb tshaj yog Inconel 718, uas muaj cov neeg kho tshuab muaj zog thiab nkag siab heev.

Vim li cas Hastelloy kim dua?

Vim tias nws muaj cov ntsiab lus molybdenum ntau dua thiab tsim los rau cov tshuaj lom neeg tsis zoo.

Ob leeg Inconel thiab Hastelloy yog siab -kev ua tau zoo nickel alloys, tab sis lawv ua haujlwm sib txawv:

Inconel → Kub & lub zog

Hastelloy → Corrosion & tshuaj tiv thaiv

👉 Xaiv cov hlau zoo tuaj yeem txo qhov kev pheej hmoo tsis ua haujlwm thiab txhim kho kev ua haujlwm.
