Tom qab kev daws teeb meem, Incoloy 800 Yeeb Nkab nthuav tawm cov khoom ruaj khov ntawm chav tsev kub: lub zog tensile tsis tsawg dua 500MPa, lub zog tawm los tsis pub tsawg dua 210MPa, thiab elongation tsis tsawg dua 30%. Qee qhov tshwj xeeb tuaj yeem ncav cuag lub zog tensile ntawm 600MPa, lub zog tawm los ntawm 275MPa, thiab elongation ntawm 45%, sib txuas ob lub zog thiab tawv. Nws hardness yog tswj ntawm HB Tsawg dua los yog sib npaug rau 180, muaj kev ua haujlwm zoo, thiab nws lub zog tuaj yeem txhim kho ntxiv los ntawm kev ua haujlwm txias.
astm b407 incoloy 800 seamless yeeb nkab Corrosion Resistance
Nyob rau hauv siab -kub oxidizing, carburizing, thiab nitriding cua, qhov ntom ntom oxide zaj duab xis tsim los ntawm chromium zoo tiv thaiv kev nkag mus ntawm corrosive media.
Nyob rau hauv corrosive xov xwm uas muaj leej faj thiab chlorine, nws corrosion kuj deb tshaj li ntawm 304 stainless hlau. Nyob rau hauv ib puag ncig dej hiav txwv ntawm 80℃nrog 50,000 ppm Cl⁻, txhua xyoo corrosion tus nqi qis heev.
Hauv hydrogen-ib puag ncig (4 MPa hydrogen ib nrab siab, 450 degree), nws tsis kam rau hydrogen-induced cracking yog 8-10 npaug siab dua li cov hlau tsis zoo tib yam. Tsis tas li ntawd, cov hlau no kuj muaj qhov ua haujlwm zoo rau chloride ion kev ntxhov siab corrosion, nrog rau kev ntxhov siab tseem ceeb ntawm tsis pub tsawg tshaj 250 MPa.
Cov txheej txheem ntau lawm ntawm Incoloy 800 Pipe
asme sb407 seamless alloy 800 yeeb nkab Melting txheej txheem
Los xyuas kom meej cov khoom purity, Incoloy 800 kav feem ntau siv dual txheej txheem ntawm nqus induction melting (VIM) + electroslag remelting (ESR). Cov txheej txheem no tuaj yeem tswj hwm cov ntsiab lus roj hauv cov hlau kom tsis tshua muaj siab: cov ntsiab lus oxygen (O) tsawg dua lossis sib npaug li 50 ppm, nitrogen (N) cov ntsiab lus tsawg dua lossis sib npaug li 150 ppm, txo cov kev tsis zoo hauv lub cev xws li pores thiab suav nrog, thiab txhim kho cov khoom siv kub ua haujlwm thiab corrosion kuj.
alloy n08800 welded yeeb nkab txoj kev
Cov txheej txheem tsim ntawm Incoloy 800 cov kav dej tau muab faib ua ob pawg: ua haujlwm kub thiab ua haujlwm txias. Kub ua hauj lwm feem ntau muaj xws li kub dov thiab kub extrusion, nrog rau kev kub ceev tswj nyob rau hauv ntau yam ntawm 1100-900 degree, thiab deformation tus nqi khaws cia ntawm 30-70% kom tau ib tug uniform austenitic qauv.
Kev ua haujlwm txias yog tsim nyog rau kev ua tiav ntawm nyias- cov kav dej phab ntsa (phab ntsa tuab tsawg dua lossis sib npaug li 1 hli), feem ntau yog siv cov txheej txheem kos duab txias, uas tuaj yeem ua tiav cov yeeb nkab txoj kab uas hla ntawm ± 0.1 hli, phab ntsa thickness kam rau ua ntawm ± 5%, thiab qhov ncaj ntawm Tsawg dua lossis sib npaug li 1.5 mm / m, ua tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob zoo li qub {{5}.
alloy 800 welded raj Vuam thiab Kev kho cua sov txheej txheem
Hauv welded yeeb nkab ntau lawm, nws raug nquahu kom siv ERNiCr-3 vuam hlau thiab GTAW (TIG) txheej txheem vuam. Lub purity ntawm lub shielding roj yuav tsum siab tshaj los yog sib npaug zos rau 99.995%, thiab lub interpass kub yuav tsum tau tswj ntawm 100-150 degree.
Tom qab vuam, kev kho kev daws teeb meem ntawm 1065℃± 15℃yog qhov yuav tsum tau ua, nrog rau qhov txias txias ntawm ntau dua lossis sib npaug li 55℃/ min los xyuas kom meej tag nrho cov carbides dissolution thiab tshem tawm cov vuam rhiab heev cheeb tsam. Lub welded sib koom yuav tsum xeem dhau RT Level II radiographic kuaj.
Rau qhov txias- cov kav dej ua haujlwm, kev kho tshuaj kuj tseem yuav tsum tau nyob rau ntawm qhov kub ntawm 1100-1175 degree, ua raws li kev ua kom txias sai kom ntseeg tau tias cov khoom sib xws.
