Tsis zoo li austenitic stainless hlau (xws li 304 thiab 316), uas feem ntau tsis yog-magnetic, 2205 duplex stainless hlau muaj qee yam khoom sib nqus, tab sis nws feem ntau suav tias tsis muaj zog hlau nplaum.
Txawm li cas los xij, nyob rau hauv qee qhov xwm txheej, xws li thaum cov khoom siv ua haujlwm txias (xws li dov lossis khoov), cov khoom sib nqus ntawm 2205 stainless hlau tuaj yeem pom ntau dua. Qib ntawm cov hlau nplaum yuav nyob ntawm seb qhov kev ua haujlwm txias ntawm cov hlau tau dhau los. Nyob rau hauv nws tus mob annealed, 2205 yuav qhia me me magnetism.
Vim li cas cov hlau nplaum ntawm 2205 duplex stainless hlau tseem ceeb?
Nkag siab txog cov khoom sib nqus ntawm 2205 duplex stainless hlau yog qhov tseem ceeb rau kev siv tshwj xeeb, xws li:
1.Electromagnetic shielding: Txawm hais tias 2205 stainless hlau tsis yog dav siv rau electromagnetic shielding vim nws cov hlau nplaum tsis muaj zog, kev nkag siab txog nws cov khoom sib nqus yog qhov tseem ceeb vim tias cov khoom no tuaj yeem cuam tshuam rau qee yam qauv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam electronics.
2.Welding thiab ua: Cov hlau nplaum tsis muaj zog ntawm 2205 duplex stainless hlau tuaj yeem cuam tshuam rau qee yam kev vuam thiab kev ua haujlwm. Welders tuaj yeem ntsib qee qhov kev sib nqus sib nqus thaum lub sijhawm ua haujlwm, tab sis qhov no tsis cuam tshuam rau tag nrho cov khoom siv.
3.Marine thiab tshuaj industries: Hauv kev lag luam uas cov ntaub ntawv raug chloride- nplua nuj ib puag ncig, cov hlau nplaum tsis muaj zog ntawm 2205 stainless hlau feem ntau tsis cuam tshuam piv rau nws zoo heev corrosion kuj thiab lub zog. Hauv cov kev lag luam no, nws qhov kev tiv thaiv rau pitting corrosion, crevice corrosion, thiab kev ntxhov siab corrosion cracking yog qhov tseem ceeb tshaj nws cov khoom sib nqus.
