Nimonic 75 GH3030 / UNS N06075 Tshuaj muaj pes tsawg leeg: Cov ntsiab lus thiab cov qauv
Nimonic 75 (UNS N06075), feem ntau hu ua GH3030 (Suav tus qauv) los yog W.Nr. 2.4951/2.4630 (German standard), yog npib tsib xee-chromium alloy (nickel-chromium ratio kwv yees li 80/20) tsim los rau siab tshaj . Nws yog ib qho kev daws teeb meem - ua kom muaj zog alloy uas, los ntawm kev tswj xyuas ntxiv ntawm titanium thiab carbon, nthuav tawm cov oxidation zoo heev thiab lub zog nruab nrab.
Dab tsi yog cov khoom ntawm NIMONIC 75?
Nimonic 75 (UNS N06075) yog 80/20 npib tsib xee-chromium alloy. Nws cov ntsiab lus tseem ceeb yog npib tsib xee, nrog cov ntsiab lus chromium ntawm 18.0% -21.0%, thiab me me ntawm titanium thiab carbon. Nws muaj qhov ua tau zoo oxidation tsis kam thiab siab - qhov kub thiab txias, thiab feem ntau yog siv rau hauv cov roj turbines thiab cov khoom siv hluav taws xob. Nws kuj muaj me me ntawm hlau, silicon, thiab manganese.
1. Taw qhia rau Nimonic 75
Nimonic 75 yog ib qho ntawm qhov ntxov tshaj plaws tsim high -kub npib tsib xee-chromium alloys. Tsis zoo li nag lossis daus- hardening Nimonic alloys, nws feem ntau txhim kho nws lub zog los ntawm kev daws teeb meem ntxiv dag zog thiab ua haujlwm hardening. Nws zoo heev oxidation kuj thiab microstructure stability ua rau nws haum rau kub txog li 1000 degree.

3. Cov ntsiab lus tshuaj muaj pes tsawg leeg ntawm Nimonic 75 Alloy
Lub luag haujlwm ntawm Nickel (Ni)
Nickel tsim lub hauv paus ntawm Nimonic 75 thiab muab kev tiv thaiv zoo rau siab -kub oxidation thiab corrosion. Nws kuj tseem txhawb nqa kom zoo ductility thiab kev ruaj ntseg ntawm qhov kub siab.
Cov nyhuv ntawm Chromium (Cr) ntawm Oxidation Resistance
Chromium yog lub luag haujlwm rau kev tsim cov txheej txheem oxide tiv thaiv ntawm cov hlau nplaum. Cov oxide zaj duab xis no tiv thaiv oxidation ntxiv thiab ua kom cov hlau muaj kev ruaj ntseg nyob rau hauv siab - qhov kub thiab txias ib puag ncig xws li lub cub tawg thiab roj turbines.
Hlau (Fe) Cov ntsiab lus tswj
Hlau yog tam sim no raws li lub hauv paus ntsiab lus thiab pab txo cov nqi alloy thaum tuav lub zog ntawm cov qauv. Txawm li cas los xij, cov ntsiab lus hlau ntau dhau tuaj yeem txo oxidation tsis kam, yog li nws cov nyiaj tau ua tib zoo tswj.
Cov pa roj carbon (C) thiab nws qhov cuam tshuam rau cov khoom
Carbon txhim kho lub zog los ntawm kev tsim carbide tab sis yuav tsum nyob hauv qhov txwv nruj. Cov pa roj carbon ntau tuaj yeem txo cov ductility thiab ua rau muaj kev cuam tshuam rau kev tawg thaum vuam.
Lub luag haujlwm ntawm Silicon (Si)
Silicon pab txhawb oxidation tsis kam los ntawm kev txhim kho kev ruaj ntseg ntawm oxide txheej tsim rau ntawm cov hlau nplaum. Nws kuj pab nyob rau hauv deoxidation thaum lub sij hawm melting txheej txheem.
Lub luag haujlwm ntawm Manganese (Mn)
Manganese pab tshem tawm sulfur impurities thaum lub sij hawm tsim cov hlau thiab txhim kho kub- ua hauj lwm zog. Nws kuj pab txhawb rau tag nrho cov alloy stability thaum tsim khoom.
Tswj cov kab ke xws li Sulfur (S)
Sulfur thiab lwm yam kab kawm yuav tsum tau ua tib zoo tswj vim tias lawv tuaj yeem ua rau kub luv thiab txo cov neeg kho tshuab kev ncaj ncees ntawm qhov kub thiab txias.
