Tshuaj muaj pes tsawg leeg ntawm 5086
5086 yog ib qho uas tsis yog-kub- kho tau Al-Mg alloy nrog cov nominal muaj pes tsawg leeg ntawm magnesium 3.5-4.5%, manganese 0.20-0.70%, silicon max 0.40%, hlau max 0.50%, chromium 0.05% max.5% zinc. 0.15%, thiab tooj liab max 0.10%, nrog rau qhov sib npaug ntawm txhuas. Nws lub zog yog feem ntau tau los ntawm kev daws teeb meem ntxiv dag zog, strain hardening, thiab tswj cov alloy lub microstructure es tsis yog nag lossis daus hardening. Cov ntsiab lus siab magnesium kuj muab kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv corrosion thaum tswj xyuas qhov qis qis cuam tshuam nrog aluminium alloys.
Yog vim li cas Al-Mg System muab kev tiv thaiv corrosion zoo
Magnesium strengthens the aluminum matrix while maintaining relatively low density, allowing 5086 to provide useful structural strength without the weight penalty of steel. Aluminium ib txwm ua ib txheej oxide nyias thaum raug huab cua lossis dej, thiab zaj duab xis passive no pab tiv thaiv cov hlau hauv qab los ntawm kev xeb ntxiv hauv ntau qhov kev pabcuam. Manganese thiab chromium pab tswj cov qauv nplej thiab txhim kho kev tiv thaiv rau qee cov ntaub ntawv hauv zos corrosion. Txawm li cas los xij, qhov ntev ntev ntawm qhov kub siab tuaj yeem cuam tshuam rau microstructure ntawm siab -magnesium alloys, yog li thermal keeb kwm yuav tsum tau txiav txim siab rau cov ntawv thov tseem ceeb. Ua kom raug thiab tsim nyog tempered 5086 muab kev tiv thaiv zoo rau cov dej hiav txwv thiab cov tshuaj chloride-ib puag ncig, thiab hauv cov tshuaj chloride- nplua nuj ib puag ncig nws yog feem ntau nyiam dua cov alloys xws li 6061 thaum corrosion kuj thiab weldability yog cov qauv tsim loj.
Mechanical Properties los ntawm Temper
Cov neeg sawv cev ntawm cov khoom siv sib txawv rau 5086-H116 hauv marine kev pabcuam yog lub zog tensile ntawm txog 290-330 MPa, yield zog ntawm txog 195-240 MPa, thiab elongation ntawm txog 10-12%. Rau 5086-H32 lossis H34, tus neeg sawv cev qhov tseem ceeb yog lub zog tensile ntawm txog 290-350 MPa, tawm lub zog ntawm 200-280 MPa, thiab elongation ntawm li 6-10%. Cov khoom muaj tseeb nyob ntawm daim ntawv ntawm cov khoom, phab ntsa thickness, temper, manufacturing method, thiab cov khoom siv specification. Rau kev siv cov txheej txheem marine, H116 thiab H321 feem ntau tau teev tseg qhov twg yuav tsum tau ua kom muaj zog tiv thaiv exfoliation thiab intergranular corrosion. Rau cov phaj thiab daim ntawv siv hauv kev tsim kho marine, ASTM B928 yog ib qho tseem ceeb siv tshwj xeeb, thaum cov khoom siv raj ua raws li lawv qhov siv tau thiab cov qauv khoom.
5086 vs 6061 hauv Chloride Ib puag ncig
Nyob rau hauv ib puag ncig chloride, 5086 tubing muaj kev ua tau zoo heev nrog feem ntau zoo pitting tsis kam thiab haum rau kev pabcuam hauv hiav txwv, thaum 6061 muab kev ua haujlwm nruab nrab nrog qis pitting tsis kam hauv cov tshuaj chloride. Ob lub alloys weld zoo, tab sis 6061 poob ntau lub zog nyob rau hauv weld - thaj chaw cuam tshuam . 5086 feem ntau yog qhov zoo rau kev ntxhov siab - kev txiav txim siab corrosion thaum ua tiav, thiab kev siv marine feem ntau suav nrog cov qauv marine, seawater systems, thiab welded Cheebtsam, thaum 6061 suits thav duab, kev txhawb nqa, thiab cov khoom siv dav dav dav - lub hom phiaj ntawm cov qauv hlau uas muaj extrusion muaj, machining, thiab qhov yooj yim ntawm qhov teeb meem, tab sis rau cov tshuaj chloride tsis tu ncua los yog dej hiav txwv raug, 5086 tuaj yeem muab qhov sib npaug zoo dua ntawm kev tiv thaiv corrosion thiab weldability.
Daim ntawv thov
5086 tubing yog siv nyob rau hauv shipbuilding thiab offshore qauv xws li cov qauv hull, decks, deckhouses, marine taug kev, railings, thiab cov qauv kev txhawb nqa. Nws yog siv rau hauv kev xaiv lub siab- nkoj thiab cov ntawv thov cryogenic vim nws qhov kev sib txuas zoo thiab cov khoom muaj txiaj ntsig qis- qhov kub thiab txias ua haujlwm, raug rau lub siab siv tau- nkoj code. Nws ua haujlwm rau cov khoom siv tshuaj lom neeg uas cov hlau tsis muaj kev tiv thaiv corrosion yog sib xws nrog cov txheej txheem nruab nrab, cov khoom siv hluav taws xob siv dej los yog dej hiav txwv ua qhov nruab nrab txias, thiab xaiv qis - mus rau nruab nrab- siab marine piping thiab seawater systems qhov twg alloy compatibility, phab ntsa thickness, vuam txheej txheem, thiab galvanic tiv thaiv kom zoo.
Vuam thiab Fabrication Notes
5086 tuaj yeem txuas nrog MIG thiab TIG cov txheej txheem, nrog 5356 thiab 5183 muab tub lim hlau feem ntau txiav txim siab rau Al-Mg alloys. Thaum tshav kub kub input thiab interpass kub yuav tsum tau tswj vim hais tias kub heev yuav hloov lub microstructure ntawm high-magnesium alloys. Vim tias 5086 tsis yog -kub- kho tau, nws lub zog tsis rov qab los ntawm cov txheej txheem nag lossis daus tom qab vuam, yog li kev npau taws thiab kev tsim cov txheej txheem yuav tsum tau txiav txim siab ua ke. Galvanic corrosion yuav tsum tau tswj nrog cov fasteners sib xws thiab kev sib cais, txij li kev sib cuag ncaj qha ntawm txhuas thiab tooj liab - muaj cov alloys lossis carbon steel hauv dej hiav txwv tuaj yeem tsim galvanic corrosion.
