Duralumin vs Stainless hlau - Qhov txawv yog dab tsi?

Duralumin vs Stainless hlau – 1. Txhais

Duralumin yog dab tsi?

Duralumin yog ib qho txhuas-raws li alloy uas feem ntau muaj tooj liab, magnesium, thiab qee zaum lwm yam xws li manganese, silicon, thiab zinc. Nws yog cov khoom siv hnyav nrog lub zog siab thiab zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv kev sib piv rau cov ntshiab txhuas. Lub sij hawm "duralumin" yog cov cim lag luam los ntawm Aluminium Association thiab hais txog cov chav kawm tshwj xeeb ntawm cov alloys uas ua tau raws li qee qhov kev xav tau ntawm cov khoom siv thiab cov cuab yeej cuab tam.

Lub ntsiab kom zoo dua ntawm duralumin yog nws lub teeb yuag ua ke nrog lub zog zoo, ua rau nws zoo tagnrho rau cov ntawv thov uas txo qhov hnyav yog qhov tseem ceeb, xws li cov khoom siv dav hlau, cov khoom siv tsheb, thiab cov khoom ua si. Txawm li cas los xij, nws cov kev tiv thaiv corrosion tsis zoo dua li qee cov alloys, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.

Stainless hlau yog dab tsi?

Stainless hlau yog hlau-raws li alloy uas muaj qhov tsawg kawg nkaus ntawm 10.5%chromium, uas muab nws cov khoom tiv thaiv corrosion. Nws yog cov khoom siv ntau yam nrog ntau qib, txhua qhov sib txawv ntawm kev sib txawv ntawm lub zog, toughness, corrosion kuj, thiab lwm yam khoom. Stainless hlau tau muab faib ua ntau hom raws li nws cov microstructure, feem ntau yogAustenitic, Martensitic, Ferritic, thiabDuplex.

Austenitic stainless hlau, xws li qib304thiab316, yog qhov siv dav tshaj plaws vim nws zoo heev corrosion kuj, ductility, thiab weldability. Nws feem ntau pom muaj nyob rau hauv cov ntawv thov xws li cov khoom siv hauv chav ua noj, cov khoom siv tshuaj lom neeg, thiab cov khoom siv vaj tsev. Martensitic thiab Ferritic stainless hlau yog cov hlau nplaum ntau dua thiab muaj zog dua tab sis tsawg dua corrosion-resistant, thaum Duplex stainless hlau muaj qhov sib npaug ntawm lub zog thiab corrosion kuj.

Duralumin vs Stainless hlau – 2. Qhov txawv tseem ceeb

Kev sib xyaw: Duralumin feem ntau yog aluminium alloy, thaum stainless hlau yog hlau-chromium alloy. Qhov sib txawv tseem ceeb no cuam tshuam rau lawv lub cev, kev tiv thaiv corrosion, thiab kev siv.

Qhov hnyav thiab hnyav: Duralumin yog qhov sib dua li cov hlau tsis muaj steel, ua rau nws zoo tagnrho rau kev siv hnyav-rhiab heev.

Lub zog thiab Toughness: Stainless hlau, tshwj xeeb tshaj yog qib Austenitic, muaj lub zog zoo thiab tawv tab sis tsis muaj zog li qee cov duralumin alloys. Txawm li cas los xij, nws tuaj yeem ntxiv dag zog los ntawm kev kho cua sov thiab ua haujlwm txias.

Corrosion Resistance: Stainless hlau, tshwj xeeb tshaj yog qib zoo li 316, muaj kev tiv thaiv corrosion zoo dua hauv kev sib piv rau duralumin, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav xws li dej ntsev lossis tshuaj lom neeg nplua nuj. Duralumin tus corrosion kuj yog qhov zoo tab sis tsis muaj zog.

Nqi: Stainless hlau feem ntau kim dua duralumin vim nws cov khoom siv ntau dua thiab cov kev xav tau ua.

Kev ua haujlwm thiab Fabrication: Ob qho khoom siv tuaj yeem ua haujlwm thiab tsim siv ntau yam txuj ci, tab sis stainless hlau yuav xav tau cov cuab yeej tshwj xeeb thiab cov txheej txheem ntau dua vim nws qhov nyuaj.

Xaus

Thaum sib piv duralumin vs stainless hlau, nws yog ib qho tseem ceeb uas yuav tau xav txog cov khoom tshwj xeeb thiab cov kev xav tau ntawm daim ntawv thov. Duralumin muaj lub teeb yuag thiab zoo corrosion kuj tab sis tsis muaj zog li stainless hlau nyob rau hauv ib puag ncig hnyav. Stainless hlau, ntawm qhov tod tes, muaj superior corrosion kuj, lub zog, thiab toughness tab sis hnyav dua thiab kim dua.
