Dab tsi Ua 5086 Marine Alloy
5086 belongs rau 5xxx series, uas nws cov ntsiab lus alloying yog magnesium, feem ntau 3.5 txog 4.9 feem pua hauv qib no. Magnesium muab cov alloy rau nws tus kheej- kho oxide zaj duab xis uas tiv taus pitting thiab kev ntxhov siab corrosion hauv dej ntsev, uas yog vim li cas 5086 tau teev tseg rau cov hulls, decks thiab offshore cov qauv uas siv ntau xyoo nyob rau hauv marine raug. Lub H32 npau taws, ua los ntawm kev ua haujlwm txias ua raws li kev ruaj ntseg, nce lub zog thaum tuav cov kev tiv thaiv corrosion ntawm tsev neeg hlau. Qhov tshwm sim yog ib daim ntawv thiab phaj khoom uas yog kwv yees li ob-feem peb sib zog dua hlau, yog li cov nkoj tsim los ntawm nws nqa hnyav dua thiab siv roj tsawg, thaum cov khoom siv nws tus kheej tsis xav tau hnyav los tiv thaiv{11}}corrosion txheej txheej.
Cov khoom tseem ceeb hauv Marine Service
Nyob rau hauv H32 temper, 5086 phaj feem ntau qhia tau hais tias lub zog tensile ntawm 290 mus rau 330 MPa thiab qhov tsawg kawg nkaus lub zog ntawm kwv yees li 215 MPa, txaus los nqus yoj cuam tshuam thiab lub hauv siab siab yam tsis tas yuav deformation. Cov alloy ntom ntawm li 2.66 g ib cubic centimeter khaws cov teeb pom kev zoo, thiab nws cov formability tso cai rau txias bending rau hauv nkhaus hull panels, lawj contours thiab complex Cheebtsam yam tsis muaj cracking. Vuam yog ncaj nraim nrog 5xxx muab tub lim xws li ER5356, uas tsim cov pob qij txha uas ua kom lawv lub zog thiab corrosion kuj nyob rau hauv dej ntsev. Cov khoom no raug txheeb xyuas raws li daim ntawv thov thiab phaj qauv, thiab cov neeg yuav khoom hauv hiav txwv ib txwm xav tau daim ntawv qhia txog cov khoom siv rau txhua pawg.
5086 piv rau Lwm Cov Khoom Siv Marine
Piv nrog carbon steel, 5086 tshem tawm qhov kev xav tau ntawm lub hauv paus tseem ceeb thiab rov ua dua los tiv thaiv - xeb xim, vim nws tsis tsim cov xoob, expansive xeb uas steel tsim. Piv nrog rau 5083, lwm yam marine alloy, 5086 feem ntau yooj yim dua rau hauv cov duab nkhaus thaum muab tus cwj pwm zoo sib xws, uas yog vim li cas cov neeg tsim cov nkoj me feem ntau nyiam nws. Piv nrog rau cov hlau tsis muaj steel, 5086 txiav qhov hnyav hnyav thiab tsis txhob muaj kev sib tsoo uas tuaj yeem cuam tshuam rau cov khoom siv tsis zoo hauv cov dej hiav txwv. Piv nrog rau fiberglass, aluminium phaj muaj zog dua nyob rau hauv kev cuam tshuam, yooj yim rau kho, thiab tag nrho recyclable thaum kawg ntawm lub nkoj lub neej.
Marine thiab Offshore Applications
Hauv kev tsim cov nkoj, 5086 phaj yog siv rau cov hulls, decking thiab bulkheads nyob rau hauv gauges li ntawm 4 hli mus rau 12 hli, qhov formability thiab dej ntsev kuj tseem ceeb tshaj plaws. Offshore zog cov qauv siv cov phaj tuab, kwv yees li 6 hli mus rau 15 hli, rau kev taug kev, railings thiab subsea clamps uas yuav tsum muaj sia nyob ntsev tsuag thiab thauj khoom tas li. Cov ntug hiav txwv dej xws li marina docks, piers thiab seawall panels yog tsim los ntawm 8 hli mus rau 20 hli phaj uas zam tidal immersion thiab yoj cuam tshuam nrog kev saib xyuas qis. Cov khoom siv nkoj suav nrog cov kaus mom, cov thawv ntim khoom thauj thiab nuv ntses- cov nkoj tuav lub nkoj siv 3 hli mus rau 8 hli daim ntawv, thiab cov ntawv siv yachting siv 2 hli mus rau 6 hli rau cov tawv nqaij ntawm lub cev, lub taub hau thiab cov kab txiav uas yuav tsum tuav kom huv si hauv cov cua ntsev.
Fabrication and Handling Tips
Rau kev txiav, plasma txiav nrog nitrogen pab roj txo cov oxide buildup uas tuaj yeem npub ntawm qhov chaw, thiab cov ntawv nyias nyias tuaj yeem pom nrog cov nplua - hniav hniav nrog cov kab txiav taped kom tsis txhob khawb. Rau welding, 5xxx muab tub lim hlau xws li ER5356 phim cov alloy muaj pes tsawg leeg, thiab qhov chaw vuam yuav tsum tau ntxuav nrog stainless hlau hlau txhuam tom qab vuam kom tshem tawm oxide zaj duab xis. Rau kev tsim, ib tug xovxwm nres nrog ib tug dav tuag, li ntawm ob mus rau peb lub sij hawm ntawm daim ntawv thickness, tsis txhob creasing, thiab nruj radii yuav tsum tau tsim nrog incremental dabtsi yog khoov. Rau kev ua tiav, txheej txheej anodized lossis marine- qib hmoov txheej ntxiv kev tiv thaiv hauv cov dej hiav txwv huab cua, thaum cov qauv hull xav tau me ntsis ntau dua li lub teeb tawg thiab xaiv xim vim tias cov yeeb yaj kiab oxide ntuj ua haujlwm tseem ceeb. Khaws cov ntawv nrog cov yeeb yaj kiab tiv thaiv thiab cov hnab looj tes huv kom txog thaum kev teeb tsa, vim tias khawb thiab cov roj ntawm tes tuaj yeem ua cov ntsiab lus pib rau corrosion.
FAQ
Npaum li cas ntawm 5086 feem ntau yog siv rau hauv hiav txwv?
H32 yog tus qauv xaiv rau kev tsim kho marine dav dav, thaum H34 muaj lub zog ntau dua rau cov khoom siv sab nrauv thiab O temper muab qhov siab tshaj plaws formability rau cov duab kev cai.
Vim li cas 5086 zoo dua li txhuas txhuas hauv dej ntsev?
Cov ntsiab lus ntawm 3.5 mus rau 4.9 feem pua magnesium txhawb kev ruaj khov, tus kheej - kho oxide zaj duab xis uas tiv taus pitting thiab kev ntxhov siab corrosion, yog li 5086 khaws nws txoj kev ncaj ncees qhov chaw dav dav - lub hom phiaj alloys yuav degrade.
5086 phaj puas tuaj yeem welded rau cov khoom sib dhos?
Tau. 5086 welds zoo siv 5xxx muab tub lim hlau xws li ER5356, thiab ua kom cov pob qij txha kom ruaj khov thiab tiv thaiv corrosion hauv marine kev pabcuam.
Lub thickness ntawm 5086 yog dab tsi rau lub nkoj hulls?
Me me mus rau nruab nrab lub nkoj hulls, decking thiab bulkheads yog feem ntau ua los ntawm 4 hli mus rau 12 hli phaj, nrog nyias daim ntawv rau yachting trim thiab thicker phaj rau offshore lug.
Puas yog 5086 xav tau kev tiv thaiv txheej hauv dej hiav txwv?
Tsis muaj txheej yuav tsum tau rau lub alloy nws tus kheej; nws oxide zaj duab xis muab kev tiv thaiv corrosion. Anodizing lossis hmoov txheej yog xaiv tau rau huab cua sab nrauv los yog pom.
