Kukho iiyantlukwano ezibalulekileyo phakathi kwe-duplex steel stainless steel mesh 2205 kunye ne-2207 kwiinkalo ezininzi. Oku kulandelayo luhlalutyo oluneenkcukacha kunye nesishwankathelo somahluko wabo:
Ukwakheka kweekhemikhali kunye nomxholo wento:
2205 duplex steel stainless: ubukhulu becala yenziwe nge-21% yechromium, i-2.5% ye-molybdenum kunye ne-4.5% ye-nickel-nitrogen alloy. Ukongezelela, iqulethe inani elithile le-nitrogen (0.14 ~ 0.20%), kunye nemilinganiselo encinci yezinto ezifana nekhabhoni, i-manganese, i-silicon, i-phosphorus kunye ne-sulfure.
2207 Duplex Stainless Steel (ekwaziwa njenge F53): Kwakhona iqulethe i-21% yechromium, kodwa inomxholo ophezulu we-molybdenum kunye ne-nickel kune-2205. Umxholo othile unokwahluka kancinci ngenxa yemigangatho eyahlukeneyo okanye abavelisi, kodwa ngokubanzi umxholo we-molybdenum uphezulu kwaye umxholo we-nickel nawo uphezulu.
Iimpawu zokusebenza:
2205 intsimbi ephindwe kabini:
Unamandla aphezulu kunye nokuqina kwempembelelo elungileyo.
Inokumelana okulungileyo jikelele kunye nendawo yokuchasana noxinzelelo lwe-corrosion.
Ngenxa yomxholo ophezulu we-chromium, i-molybdenum kunye ne-nitrogen ekubunjweni kwayo kweekhemikhali, inomlinganiselo ophezulu we-anti-pitting corrosion (ixabiso le-PREN 33-34). Phantse kuyo yonke imithombo yeendaba ezonakalisayo, ukuxhathisa kwe-corrosion kwi-pitting kunye nokuchasana kokubola kwe-crevice kungcono kune-316L Okanye i-317L i-austenitic stainless steel.
2207 intsimbi ephindwe kabini:
Inokumelana ne-corrosion engcono kunye nokumelana nokunxiba, ngakumbi ngokuchasene neendaba ezitshabalalisayo ezifana ne-acids ezomeleleyo, ii-alkali kunye ne-chloride ion.
Inamandla aphezulu kunye nokuqina kwaye yomelele ngakumbi kunentsimbi eqhelekileyo engenasici.
Ineplastiki elungileyo kunye nokuqhubekeka, kunye nokuqina okugqwesileyo kunye nokumelana nokudinwa.
Iindawo zesicelo:
2205 duplex steel stainless: isetyenziswa kakhulu kwishishini lemichiza, i-oyile kunye negesi yegesi, ubunjineli baselwandle, ishishini lokwakha, ishishini le-aerospace kunye nezinye iinkalo. Ukumelana nokugqwesa kwayo okugqwesileyo kuyenza ibe lolona khetho lufanelekileyo lokwenziwa kweenqanawa, amaqonga angaphesheya kunye nezinye izixhobo.
2207 duplex steel stainless: ikwafanelene nemekobume eyingozi kakhulu, ngakumbi kwindawo erhabaxa efana nobunjineli baselwandle kunye neshishini lemichiza. Ngenxa yeempawu zayo zokusebenza ezizodwa, ikwasetyenziswa ngokubanzi kwiindawo ezifana ne-oyile kunye negesi yokomba.
Ukusebenza kwe-welding kunye neendleko:
I-2205 i-duplex yensimbi engenasici ine-weldability elungileyo. Ayifuni ukutshisa kwangaphambili ngexesha lokutshisa okanye unyango lobushushu emva kwe-welding, eyenza lula inkqubo ye-welding.
Ngokwahlukileyo, ukusebenza kwe-welding ye-2207 duplex stainless steel imbi kakhulu kwaye idinga iinkqubo ezikhethekileyo ze-welding. Ukongeza, ngenxa yokusebenza kwayo okuhle kakhulu, ixabiso le-2207 duplex steel stainless liphezulu kwaye ixabiso lokuvelisa liphezulu.
