Alloy 800 Sheet High -Tsub Ua Haujlwm

Alloy 800 daim ntawv (UNS N08800)Ameslikas tsim los muab tus nqi- siv tau zoo rau siab -nickel alloys thaum lub sij hawm cov hlau tsis txaus hauv xyoo 1950, nws cov hlau -nickel-chromium tshuav nyiaj li cas muaj qhov tshwj xeeb qab zib: nws yog oxidation ntau dua - tiv taus ntau dua li cov qauv stainless hlau, tsis tau ntau dua . ​​el60 series HT PIPE is aincoloy alloy 800 daim ntawvtus xa khoom nrog 15+ kev xa tawm.Tiv tauj pebkom paub ntau ntxiv thiab quotes dawb!

1. Alloy 800 (UNS N08800)

Kev tsom xam qhov tseem ceeb:General corrosion thiab oxidation kuj.

Optimal Kub:Hauv qab 1100℉ (593 degree).

Ntsiab Lus Qhia:Nws yog feem ntau annealed nyob rau hauv qis kub, ua rau ib tug finer grain qauv uas ua ntej lub zog tensile ntawm nruab nrab kub.

2. Alloy 800H (UNS N08810)

Kev tsom xam qhov tseem ceeb:Creep kuj.

Optimal Kub:Tshaj 1100℉ (593 degree).

Ntsiab Lus Qhia:Tswj cov ntsiab lus carbon (0.05% mus rau 0.10%) thiab siab -kub tshuaj anneal tsim ib coarse grain loj (ASTM 5 los yog coarser), uas yog ib qho tseem ceeb rau tiv thaiv "creep"- qeeb deformation ntawm hlau nyob rau hauv tas li kev nyuaj siab ntawm high kub.

3. Alloy 800HT (UNS N08811)

Kev tsom xam qhov tseem ceeb:Kev ntxhov siab ntau tshaj - tawg lub neej.

Optimal Kub:High -kev nyuaj siab thermal ib puag ncig.

Ntsiab Lus Qhia:Ntxiv zawm cov chemistry ntawm 800H los ntawm kev yuam kom ua ke Aluminium thiab Titanium cov ntsiab lus ntawm 0.85% mus rau 1.20%. Qhov no ua kom lub siab tshaj plaws rupture lub zog nyob rau hauv lub series.

Kev ua tau zoo nyob rau hauv Aggressive Environments

Alloy 800 daim ntawv yog engineered los tswj cov tshuaj "sib ntaus sib tua" uas yuav degrade tus qauv 300-series stainless hlau.

• Oxidation Resistance:Cov ntsiab lus chromium siab ua rau muaj kev tiv thaiv, ua raws li qhov ntsuas uas tiv thaiv kev sib sib zog nqus hlau los ntawm oxygen, txawm tias thaum caij tsheb kauj vab nrawm.
• Carburization kuj:30--35% npib tsib xee cov ntsiab lus ua qhov cuam tshuam rau kev nqus cov pa, ua cov ntawv no zoo tagnrho rau cov roj av "cracker" raj thiab cov pob tawb kho cua sov uas muaj cov pa roj carbon ntau.
• Sulfidation Stability:Tsis zoo li cov hlau nplaum uas muaj cov ntsiab lus nickel siab heev, cov hlau- puag ntawm Alloy 800 muab kev tiv thaiv zoo dua rau sulfur-cov kabmob gases, uas tuaj yeem ua rau "kub corrosion."

Fabrication thiab Welding Considerations

Ua haujlwm nrog Alloy 800 daim ntawv yuav tsum tau ua raws li cov txheej txheem tshwj xeeb los tswj nws cov corrosion-cov khoom tiv taus:

• Vuam:SivInconel Filler Hlau 82los yogVuam Electrode 182rau feem ntau daim ntawv thov. Yog tias daim ntawv yuav raug rau qhov kub thiab txias qhov twg nkag yog qhov tseem ceeb (qhov 800H / HT ntau), sivIb 617los yogHaynes 230fillers kom phim lub siab - kub lub zog ntawm lub hauv paus hlau.
• Machining:Vim nws yog austenitic alloy, nws ua haujlwm - hardens sai. Siv cov khoom hnyav- cov khoom siv ua haujlwm, cov cuab yeej ntse, thiab tus nqi noj khoom noj tas li kom nyob twj ywm "hauv" ua haujlwm- thaj tsam tawv.
• Kev tsim:Alloy 800 muaj qhov txias txias zoo heev - tsim cov yam ntxwv zoo ib yam li 316 stainless hlau, txawm tias yuav tsum muaj zog ntau dua vim nws lub zog ntau dua.

FAQ

Q: Vim li cas Alloy 800 nyiam dua Stainless Hlau 310 rau cov khoom siv hluav taws xob?

Thaum ob qho tib si ua tau zoo nyob rau hauv high kub, Alloy 800 muaj superior tiv tauschloride stress -corrosion crackingthiabsigma theem embrittlement. Stainless 310 tuaj yeem ua nkig tom qab ntev -lub sij hawm raug rau qhov kub thiab txias ntawm 1100℉ thiab 1500℉, whereas Alloy 800 tseem ductile, ua rau nws muaj kev nyab xeeb rau cov khoom siv uas ua rau thermal expansion.

Q: Puas yog Alloy 800 sib nqus?

No. Alloy 800 yog ib qho austenitic alloy ruaj khov thiab seemtsis yog-magneticnyob rau hauv yuav luag txhua yam kev ua. Qhov no ua rau nws tsim nyog rau cov ntawv thov tshwj xeeb hauv hluav taws xob lossis kev kho mob uas yuav tsum zam kev cuam tshuam sib nqus, txawm hais tias nws qhov siab - tus nqi kub feem ntau txwv nws rau ib puag ncig thermal.

Q: Qhov kev pabcuam siab tshaj plaws rau Alloy 800HT yog dab tsi?

Nyob rau hauv feem ntau atmospheric tej yam kev mob, Alloy 800HT yuav siv tau ntawm kub mus txog1900℉(1038 degree). Txawm li cas los xij, nws cov load-cov kabmob muaj peev xwm (tso cai rau kev ntxhov siab) poob qis heev ntawm cov kev kub ntxhov no. Rau kev siv lub nkoj siab tswj hwm los ntawm ASME cov lej, qhov ntsuas kub siab tshaj plaws feem ntau qis dua kom ntseeg tau tias muaj kev nyab xeeb siab.

Q: Puas yog Alloy 800 daim ntawv xav tau tom qab-weld heat treatment (PWHT)?

Feem ntau,tsis muaj. Alloy 800 tsis xav tau PWHT los kho corrosion lossis ductility tom qab vuam. Txawm li cas los xij, yog tias cov khoom siv tuab heev los yog daim ntawv thov cuam tshuam nrog kev caij tsheb kauj vab hnyav, kev ntxhov siab - yuav ua rau muaj kev ntxhov siab los tiv thaiv kev cuam tshuam thaum ua haujlwm.
