Incoloy 840: Feem ntau pom nyob rau hauv cov av roj, muaj zog tsim cov nroj tsuag, thiab kev lag luam uas xav tau cov ntaub ntawv uas yuav muaj qhov kub thiab txias thiab oxidation.
Incoloy 925: nquag nyob rau hauv cov roj thiab roj, petrochemical, thiab offshore cov kab lis kev vim nws zoo tshaj plaws tiv thaiv corrosion thiab kev nyuaj siab tawg nyob rau hauv ib puag ncig corrosive heev.
3. Dab tsi yog cov txiaj ntsig ntawm kev siv Incoloy 800, 825, 840, thiab 925 alloys rau cov ntawv thov kub siab?
Teb:
Tag nrho cov alloys muab kev tiv thaiv zoo heev rau oxidation, carburization, thiab kub-ntsuas qhov ntsuas. Tshwj xeeb:
Incoloy 800: siab tsis kam rau oxidation thiab carburization ntawm qhov kub thiab txias txog li 1100℃(2012℃(2012 Degree F), ua rau nws muaj kev sib tw ntev.
Incoloy 825: Qhov zoo tagnrho rau cov kev siv tshuaj ntsuam kom muaj kev kub ntxhov, nrog Great Kuj nrog Oxidation thiab sulfidation.
Incoloy 840: Cov pa roj chromium ntau tso cai rau kev tshwj xeeb rau oxidation ntawm qhov kub tshaj 1100℃(2012 DEGREEN F) thiab cua sov cov tshuab thiab cua sov.
Incoloy 925: Ua rau zoo heev rau ob qho oxidation thiab corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas chloride thiab hydrogen sulfide sprosity yog ib qho.
4. Yuav ua li cas cov cuab yeej siv tshuab ntawm Incoloy 800, 825, 840, thiab 925 sib piv?
Teb:
Incoloy 800: zoo tensile lub zog (txog 80 ksi) thiab siab nkag dag zog, zoo heev rau kev tswj kev ncaj ncees ntawm kev kub siab.
Incoloy 825: Lub zog zoo sib xws tab sis nrog qhov zoo dua tsis kam mus rau kev ntxhov siab rau cov molybdenum thiab cov ntsiab lus tooj liab, ua rau nws zoo dua rau cov acidic ib puag ncig.
Incoloy 840: High tensile lub zog thiab zoo heev creep kuj, tshwj xeeb tshaj yog thaum nce kub. Nws tau qis dua qis dua qhov ua haujlwm qis dua piv rau 800 thiab 825 alloys vim nws cov ntsiab lus chromium siab dua.
Incoloy 925: Muab cov tshuaj tiv thaiv tensile thiab tiv taus ob qho tib si corrosion thiab kev ntxhov siab corrosion. Nws muaj qhov ntau dua cov txiaj ntsig lub zog sib piv rau lwm yam kev nkag mus rau lwm tus.
5. Dab tsi yog cov kev sib tw uas ib txwm muaj thaum Vuam incase 800, 825, 840, thiab 925 cov ntaub ntawv?
Teb:
Vuam incoloy alloys nthuav qhia qee qhov kev sib tw vim lawv cov ntsiab lus npib tsib xee thiab rhiab rau kev kho cua sov:
Incoloy 800: nquag carbide nag lossis kub, uas tuaj yeem txo cov corrosion tsis kam. Preheating thiab tom qab weld kev kho cua sov feem ntau yuav tsum tau tiv thaiv qhov no.
Incoloy 825: Lub siab Molybdenum cov ntsiab lus tuaj yeem ua rau nws nyuaj rau weld tsis muaj cov koom ua ke ua haujlwm. Yuav tsum muaj kev saib xyuas tshwj xeeb kom tsis txhob tawg hauv qhov kub-cuam tshuam cheeb tsam (hz).
Incoloy 840: Vim tias nws cov ntsiab lus chromium siab, cov alloy tuaj yeem yog nquag mus rau intergranular corrosion thaum vuam. Ua tib zoo saib tshav kub thaum lub sij hawm vuam yog qhov tseem ceeb kom zam dhau qhov no.
Incoloy 925: Xav tau cov kev tswj kom meej thaum sawv los tiv thaiv kev sawv cev thiab tawg, tshwj xeeb tshaj yog nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam. Ib qho kev muab cov hlau sib dhos nrog cov muaj feem sib xyaw ua ke yog feem ntau yuav tsum muaj kev tswj hwm corrosion.
