Vim li cas 5052 rau Marine Service
5052 yog ib qho txhuas-magnesium alloy nyob rau hauv uas magnesium yog thawj alloying caij, muab cov khoom zoo heev tiv thaiv dej hiav txwv thiab ntsev - tshuaj tsuag ib puag ncig. Piv nrog rau cov alloys xws li 3003 thiab 6061, 5052 ua tau zoo dua nyob rau hauv chloride- nplua nuj tej yam kev mob thiab yog li muab cais raws li marine- qib alloy. Nws muaj zog qaug zog zoo thiab muaj kev cuam tshuam tsis zoo rau nyias - ntsuas cov yam ntxwv ntawm qhov chaw, kev tsim tau zoo nrog kev ua haujlwm nruab nrab, thiab cov lus teb zoo rau anodizing rau ob qho tib si tiv thaiv thiab kho kom zoo nkauj tiav.
Tshuaj muaj pes tsawg leeg
Feem ntau muaj pes tsawg leeg rau 5052 yog txhuas raws li qhov sib npaug, magnesium 2.2-2.8%, chromium 0.15-0.35%, manganese mus txog 0.10%, hlau mus txog 0.40%, silicon txog 0.25%, tooj liab mus txog 0.10%, zinc mus txog 1%. Magnesium muab kev tiv thaiv corrosion, thaum chromium tswj cov qauv nplej thiab txhim kho kev ua haujlwm corrosion. Cov txiaj ntsig tau muab los ntawm EN AW-5052, ASTM B209, thiab AMS-QQ-A-250, thiab daim ntawv pov thawj zeb muab cov lej tseeb rau txhua qhov khoom xa tuaj.
Tempers thiab Mechanical Properties
5052 tsis yog-kub- kho tau; lub zog yog tiav los ntawm strain hardening. O temper yog tag nrho annealed nrog siab tshaj plaws ductility rau kev sib sib zog nqus nqus. H32 yog strain-hardened thiab stabilized, muab nruab nrab lub zog thiab zoo formability rau dav marine panels. H34 nce mus txog qib siab zog nrog me ntsis poob ntawm formability rau cov txheej txheem, thiab H111 yog maj mam ntxiv dag zog rau extruded los yog txias - ua hauj lwm qhov chaw. Cov cuab yeej cuab yeej cuab tam muaj li ntawm 215-290 MPa qhov kawg tensile lub zog, 70-200 MPa yield zog, thiab 6-20% elongation nyob ntawm qhov kub thiab txias. Qhov ceev yog hais txog 2.68 g / cm3 nrog ib tug modulus ntawm elasticity ntawm txog 69 GPa.
Fabrication thiab koom ua ke
5052 muaj qhov txias txias zoo heev: O temper suits sib sib zog nqus nqus, thaum H tempers yog siv rau khoov thiab nruab nrab txoj kev. Nws welds tau yooj yim nrog TIG, MIG, thiab cov txheej txheem vuam tsis kam, nrog ER5356 lossis ER4043 raws li cov khoom siv hlau. Fasteners yuav tsum yog stainless hlau los yog coated, nrog insulating washers tiv thaiv galvanic corrosion ntawm dissimilar hlau. Machining yog ncaj nraim, txawm hais tias cov chips yog ductile thiab yuav tsum tau khiav tawm kom raug. Kev taw qhia tsim qauv rau cov khoom hauv hiav txwv suav nrog kev zam cov crevices thiab cov ntxiab dej, thiab siv cov sealants thiab cov txheej tiv thaiv ntawm cov pob qij txha.
Kev tiv thaiv corrosion thiab tu
Magnesium cov ntsiab lus muab 5052 zoo tiv thaiv dej hiav txwv thiab ntsev tsuag, tab sis pitting thiab crevice corrosion tseem tuaj yeem txhim kho yog tias cov txheej tiv thaiv puas. Anodizing, pleev xim, lossis PVDF / polyester txheej txuas ntxiv kev pabcuam lub neej, thiab kev tiv thaiv cathodic lossis anodes sacrificial anodes yuav raug siv rau cov ntawv thov submerged. Cov khoom siv yuav tsum tau muab cia kom tiaj thiab qhuav, kom deb ntawm cov hlau tsis sib xws, thiab cov pob qij txha thiab cov fasteners yuav tsum tau tshuaj xyuas tsis tu ncua nrog cov sealants thiab cov xim pleev xim rov qab siv dua li xav tau.
Cov ntawv thov Marine Hom
Cov ntawv thov feem ntau suav nrog lub nkoj hulls thiab decks, superstructures thiab pilots tsev, marine khoom thiab fittings, roj thiab dej tanks, offshore -platform taug kev thiab panels, bulkheads thiab partitions, thiab HVAC ducts nyob rau hauv ib puag ncig ntub. Rau cov tswv cuab ntawm lub hauv paus hull ntawm cov hlab ntsha loj, siab dua - lub zog alloys xws li 5083 yuav nyiam dua; 5052 yog qhov zoo tagnrho rau daim ntawv thov, fittings, thiab lwm yam qauv.
FAQ
Q: Puas yog 5052 yog marine-qib txhuas?
A: Yog. Nws 2.2-2.8% magnesium cov ntsiab lus muab kev tiv thaiv zoo rau seawater corrosion, thiab nws yog ib qho qauv marine alloy rau hulls, decks, tso tsheb hlau luam, thiab cov qauv ntawm ntug dej hiav txwv.
Q: Qhov txawv ntawm 5052-O thiab 5052-H32 yog dab tsi?
A: O yog tag nrho annealed nrog siab tshaj plaws ductility rau sib sib zog nqus nqus, thaum H32 yog strain- hardened thiab stabilized rau nruab nrab lub zog thiab zoo formability nyob rau hauv dav marine panels.
Q: 5052 puas tuaj yeem welded?
A: Yog. Nws welds nkag tau nrog TIG, MIG, thiab tsis kam vuam, siv cov fillers xws li ER5356 lossis ER4043.
Q: Cov qauv twg npog 5052 daim ntawv thiab phaj?
A: EN AW-5052 / EN 573 / EN 485, ASTM B209, AMS 4120, AMS 4013, thiab ISO 6361 feem ntau siv.
Q: Dab tsi yog cov khoom ntim tau pom zoo rau vuam 5052?
A: ER5356 lossis ER4043 yog cov kev xaiv ntau, nyob ntawm seb qhov yuav tsum tau muaj zog vuam thiab corrosion kuj.
Q: Thaum twg 5083 yuav tsum siv 5052?
A: Rau cov thawj hull cov tswv cuab ntawm cov hlab ntsha loj thiab cov kev xav tau tshaj plaws ntawm cov qauv siv, qhov twg yuav tsum muaj zog dua; 5052 haum rau daim ntawv thov, fittings, thiab lwm yam qauv.
