Hais kom faib rau AWS A5.14 thiab ASME SFA {5}}. 14 Cov Qauv}. 14 Cov Qauv} Cia elve rau nws muaj pes tsawg leeg, cov khoom, thiab cov ntawv thov tiag tiag.
Muaj pes tsawg leeg thiab cov qauv tsim mellurgical
Ernicu -7}, tseem hu ua Nickel Alloy 60, yog tsim nrog kev sib xyaw ua ke kom sib npaug thiab ua haujlwm. Nws cov tub ntxhais los ua ke suav nrog npib tsib xee (62-69%), mus txog 4%), thiab cov lej ntawm cov hlau, silem, txhuas, thiab titanium. Cov ntsiab lus Nickel siab uas ua rau muaj kev tiv thaiv kom zoo dua rau corrosion, thaum tooj liab txhim kho thermal conductivity thiab lub zog. Manganese thiab silicon ua li deoxidizers, kom cov titanium ruaj khov rau micructivure microstructure thiab minimizes porosity. Qhov no muaj cov qauv no ua rau muaj qhov muag melting ntawm kwv yees li 1,185 degree (2,165 degree ntawm 8.9 g / cm³ kub thiab ua kom muaj ib puag ncig high ill.
Neeg kho tshuab thiab cua sov cov khoom
Ernicu -7 pa nyem hauv ob qho tib si tshuab thiab cua sov ua haujlwm. The alloy exhibits a tensile strength of 480-530 MPa (70,000-77,000 psi) and a yield strength of 360 MPa (53,000 psi), ensuring robust welds that withstand structural stress. Nws lub ductility, nrog tus nqi elongation ntev txog 34%, tso cai rau kev yoog raws li kev tsim thiab rov kho dua yam tsis muaj pob txha. Thermally, ernicu -7 tswj hwm qhov kub ntawm 260 degree (500 degree rau cov ntawv thov muaj feem xyuam nrog kev sib kis tau. Tsis tas li ntawd, nws coefficient ntawm thermal expansion (13.8 x 10⁻⁶ / degree) raws li cov hlau uas tsis muaj zog nrog cov pob zeb tsis sib xws.
Corrosion Kuj
Ib qho ntawm ernicu -7 '}'} '}'} '}'} '}'} '}'} '}'} ' Nws sib zog hauv cov chaw marine, qhov twg nws tiv taus dej hiav txwv corrosion, chloride-ntxias pitting, thiab cov nyom corrosion. Hauv cov nroj tsuag ua noj, nws tiv thaiv kom raug txo cov kua qaub zoo li sulfuric zoo li sulfuric thiab hydrochloric acid, nrog rau cov kev daws teeb meem alkaline. Qhov kev tiv thaiv corrosion yog txhawb ntxiv los ntawm nws txoj kev tiv thaiv kom muaj kev ntxhov siab, ua kom muaj kev cia siab ntev hauv cov cuab yeej tseem ceeb.
Cov ntawv thov hla kev lag luam
Ernicu -7 'v versatility ua rau nws tsis tseem ceeb nyob rau hauv ntau ntawm cov haujlwm:
Marine engineering: Nws yog siv rau weld tooj liab-nickel alloys hauv nkoj thiab ntug dej hiav txwv, qhov twg tsis kam rau ntsev thiab kev tawm tsam yog qhov tseem ceeb.
Kev Lag Luam: Cov khoom siv sib koom ua ke ntawm cov khoom siv sib xyaw ua kua, xws li cov tshuaj reavel thiab cua sov.
Aerospace thiab lub zog tiam: Nws qhov kev siv hluav taws xob siab txhawb cov ntawv thov hauv cov txheej txheem tsim kho hauv kev siv hluav taws xob, ua kom muaj kev nyab xeeb nyob rau hauv cov xwm txheej huab.
Kev tsim khoom: Ernicu -7 Tus choj sib txuas nrog cov neeg tsis sib xws li Nickel alloys, Hlau, thiab Tooj Seamless thiab Pipelines.
Cov tsho hlau deg: Raws li ib qho khoom siv surfacion, nws muab cov khaubncaws sab nraud povtseg, nws muab cov khaubncaws sab nraud povtseg ntawm cov roj carbon stocket, txuas ntxiv rau lub neej ntawm cov khoom siv hnyav.
Vuam cov txheej txheem thiab kev coj ua zoo tshaj plaws
Ernicu -7 yog tau tshaj roj av hlau arc vuam (GMAW), roj tungsten arc vuam (gtawry, thiab submerged arc vuam (pom). Rau kev ua kom pom tseeb, 100% kev tiv thaiv cov roj txheem argon tau pom zoo kom tiv thaiv oxidation. Vuam qhov tsis sib txawv sib txawv ntawm xer hlau thiab cov txheej txheem; Piv txwv li, gtaw nrog 1.6mm hlau siv ntawm 14-18 volts thiab {5}} amps. Tom qab kev kho cua sov yog tsis tsim nyog, tab sis ua kom huv huv yog qhov tseem ceeb kom tshem tawm cov kev qias neeg uas tuaj yeem ua rau cov kab mob tsis kam.
Ntiaj teb cov qauv thiab cov tuam ntxhab
Paub txog uns om4060, ornicu -7 adheres rau nruj rau cov qauv thoob ntiaj teb, ua kom zoo sib xws thiab ua tau zoo. Cov thawj coj tsim khoom muab cov alloy nyob rau hauv ntau hom ntawv, suav nrog cov xaim xaim rau GMAW thiab ncaj Rods rau GTAW, catering rau ntau qhov kev lag luam muaj kev lag luam.
Tag
Ernicu -7} sawv cev ntawm cov xim hlau, ua kom sib xyaw ua ke, thiab thermal stability kom tau raws li qhov xav tau ntawm cov engineering niaj hnub no. Los ntawm marine infrastructure rau lub zog nuclear, nws lub luag haujlwm hauv kev koom nrog thiab tiv thaiv cov khoom tseem ceeb hauv ntiaj teb thoob ntiaj teb. Raws li thev naus laus zis hloov zuj zus, ornicu -7 seem ib lub pob zeb hauv siab thiab ntseeg tau cov qauv welded hauv cov chaw nyuaj tshaj plaws.
