Cov khoom siv dab tsi yog stainless hlau 32750?
32750 yog duplex stainless hlau 2507 khoom. Nws qhov ceev yog 8.03g / cm3, nws melting point yog 1300-1390 degree, thiab nws tsis yog magnetic. Kev kho cua sov yog ua kom qhov kub thiab txias ntawm 1000-1052 degree rau 1 mus rau 2 teev, ua raws li cua txias los yog dej txias. 32750 muaj cov ntsiab lus siab ntawm chromium thiab molybdenum, yog li nws muaj zog corrosion kuj, tshwj xeeb tshaj yog inorganic acids uas muaj chlorides, uas kuj muaj zog corrosion kuj. Nws yog dav siv hauv cov khoom siv roj thiab roj, kev lag luam tshuaj lom neeg, kev lag luam pipeline thiab cov khoom siv tshuab.
Alloy 32750 yog ib qho super duplex stainless hlau nkag rau hauv cov tshuaj annealed mob. Raws li ib tug superduplex stainless hlau, nws combines qhov zoo tagnrho yam ntawm austenitic thiab ferritic steel qib. Ntau cov chromium, molybdenum thiab nitrogen cov ntsiab lus ua rau Pitting Resistance Equivalency Number (PREN) > 41, muab kev ua haujlwm zoo tshaj pitting thiab crevice corrosion rau austenitic thiab duplex stainless hlau nyob rau hauv yuav luag tag nrho cov corrosive media thiab tseem ceeb pitting kub tshaj 50 degree.
Muab nyob rau hauv cov mob annealed, nws muaj ib tug yield zog ntawm 80ksi (550Mpa), siab tshaj feem ntau austenitic thiab duplex stainless hlau qib. Nws tsis tuaj yeem hardened los ntawm kev kho cua sov tab sis tuaj yeem ua kom muaj zog los ntawm kev ua haujlwm txias. Nws kuj tseem muaj qis dua coefficient ntawm thermal expansion thiab thermal conductivity ntau dua li austenitic steels, ua rau nws haum rau kev khiav hauj lwm kub txog li 300 degree. Alloy 32750 yog teev raws li NACE MR 0175 rau siv nyob rau hauv qaub ib puag ncig thiab yog ASME ntawv pov thawj rau cov hlab ntsha siab rau siv nyob rau hauv ntau yam kev siv.
GNEE Steel tau cog lus rau kev lag luam stainless hlau tau ntau xyoo thiab yog tus kws tshaj lij hauv kev lag luam stainless hlau. GNEE Steel muab cov khoom zoo stainless hlau los daws cov kev xav tau ntau yam rau koj.
