5083-H22 yog dab tsi?
5083-H22 yog ib qho uas tsis yog- cua sov- kho tau txhuas-magnesium alloy los ntawm 5xxx series. H22 temper qhia tias cov khoom tau raug strain- hardened mus rau lub quarter-hard lub xeev thiab ces ib nrab annealed los txo cov kev ntxhov siab nyob rau hauv thaum tuav ib feem ntawm lub zog tau los ntawm strain hardening. Qhov no tso cov khoom nruab nrab ntawm tag nrho cov annealed O mob thiab tag nrho hardened H28 mob, ua tiav kwv yees li ib feem peb ntawm qhov siab tshaj plaws hardness thiab muab ib tug pab tshuav nyiaj li cas ntawm lub zog, ductility, thiab corrosion kuj.
Muaj Daim Ntawv Thov
5083-H22 yog dav siv los ua phaj, raj, thiab pas nrig. Phaj yog siv nyob rau hauv kev tsim cov nkoj rau hulls, decks, thiab tso tsheb hlau luam, qhov twg nws cov corrosion kuj, formability, thiab weldability muaj nuj nqis. Tube yog tsim rau lub nkoj cua txias, cov roj thiab cov kab xa hluav taws xob, thiab cov qauv kev txhawb nqa uas yuav tsum tau khoov thiab sib sau. Qws yog siv rau fasteners, shafts, thiab structural Cheebtsam nyob rau hauv cov khoom siv marine, qhov twg temper muab ruaj khov qhov tseeb rau txoj siav thiab milling. Cov raj ntau qhov ntau thiab tsawg ntawm li 3 hli mus rau 2500 hli sab nraud txoj kab uas hla nrog phab ntsa thicknesses txog 0.2 txog 150 hli; round pas nrig feem ntau muaj los ntawm 5 hli mus rau 420 hli txoj kab uas hla, thiab square bar los ntawm 6.35 hli x 6.35 hli mus txog 150 hli x 150 hli, raws li tus neeg yuav khoom muaj peev xwm.
Tshuaj muaj pes tsawg leeg
5083 feem ntau yog txhuas nrog magnesium ua lub ntsiab alloying ntawm 4.0-4.9%, manganese ntawm 0.4-1.0%, thiab chromium ntawm 0.05-0.25%, ua ke nrog me me ntawm silicon, hlau, tooj liab, zinc, thiab titanium. Cov ntsiab lus magnesium siab yog dab tsi muab cov alloy nws zoo heev tiv thaiv dej hiav txwv thiab muaj tshuaj.
Mechanical thiab Physical Properties
Tshaj tawm cov nqi siv rau 5083-H22 suav nrog lub zog tensile kawg ntawm txog 305-380 MPa, lub zog tawm ntawm yam tsawg 215 MPa, elongation ntawm kwv yees li 8.8%, Brinell hardness nyob ib ncig ntawm 89 HB, thiab qaug zog ntawm txog 190 MPa. Lub cev siv qhov tseem ceeb muaj xws li qhov ceev ntawm 2650 kg / m3, melting thaj tsam ntawm 580-640 degrees C, thermal conductivity ntawm li 120-121 W / mK, coefficient ntawm thermal expansion ntawm txog 25 x 10-6 / K, hluav taws xob tiv taus ntawm txog 0.58 x 10-6 ohm-2 thiab modulus. Vim tias muaj cov ntsiab lus magnesium siab, qhov kev pabcuam kub feem ntau txwv rau li 65 degrees C qhov twg corrosion kuj yog qhov tseem ceeb.
Daim ntawv thov
5083-H22 yog dav siv nyob rau hauv marine lug nrog rau lub nkoj hulls, decks, thiab cia tanks; cov hlab ntsha siab rau tshuaj thiab roj cia; cryogenic tanks thiab pipelines; thiab cov khoom siv xws li thav duab, brackets, thiab kev txhawb nqa. Nws ua ke ntawm kev tiv thaiv corrosion, weldability, thiab lub zog nruab nrab ua rau nws xaiv thawj qhov twg los mus ntev rau cov dej hiav txwv.
Fabrication thiab Limitations
Cov hlau yog tsim rau stamping thiab ncab thiab welds tau yooj yim nrog MIG thiab TIG cov txheej txheem siv 5xxx-series muab tub lim xws li 5183, txawm hais tias lub zog hauv tshav kub- thaj tsam cuam tshuam yuav qis dua hauv cov khoom siv niam txiv. Machining feem ntau yuav tsum tau tshwj xeeb cov cuab yeej vim yog cov alloy lub toughness. Vim tias magnesium cov ntsiab lus siab tshaj 3.5%, kev pabcuam siab tshaj li 65 ° C yuav tsum zam qhov kev ntxhov siab - yuav tsum muaj kev tiv thaiv corrosion, thiab kev ua haujlwm txias yuav tsum ua tib zoo ua tib zoo. Piv nrog rau H32 npau taws, H22 muaj qhov sib txawv me ntsis thiab cov yam ntxwv elongation: H22 feem ntau yog siab dua hauv lub zog tensile thaum H32 muaj cov qauv zoo dua; qhov kev xaiv zaum kawg nyob ntawm seb lub zog lossis kev yooj yim ua tau zoo rau daim ntawv thov.
FAQ
Q: H22 txhais li cas hauv 5083-H22?
A: H22 txhais tau hais tias cov khoom raug strain-hardened mus rau ib lub hlis twg- lub xeev nyuaj thiab ces ib nrab annealed, muab qhov sib npaug ntawm lub zog thiab formability ntawm O thiab H28 tej yam kev mob.
Q: Puas yog 5083-H22 haum rau dej hiav txwv?
A: Yog. Nws cov ntsiab lus magnesium siab ua rau nws ua haujlwm zoo rau cov dej hiav txwv thiab cov khoom siv tshuaj, uas yog vim li cas nws yog tus qauv hauv marine engineering.
Q: Yuav 5083-H22 welded?
A: Yog. MIG thiab TIG welding nrog 5xxx-series muab tub lim xws li 5183 raug pom zoo, txawm hais tias tshav kub- thaj tsam cuam tshuam tuaj yeem txo qis zog.
