904L isishintshi sokushisa sensimbi engagqwali
Ulwazi Oluyisisekelo
I-SS 904L iwukuqukethwe kwekhabhoni ephansi okuqinisekisa ukumelana nokuzwela ngenqubo yokushisela futhi isiza ekuvimbeleni ukugqwala kwe-intergranular.Amashubhu okushisa aleli banga athandwa kakhulu phakathi kwabathengi ngenxa yezakhiwo zawo ezinhle.
ikhwalithi ephezulu ye-Stainless Steel 904L Heat Exchanger Tubes kubathengi bawo emhlabeni wonke.Imboni isifike kude ekubeni sesikhundleni esiphezulu emakethe ngenxa yeminyaka yokusebenza kanzima kanye nesipiliyoni.Abathengi banikezwa ngekhwalithi ephezulu yamashubhu okushintshanisa ukushisa ngentengo yokuncintisana kakhulu.Izinto ezingavuthiwe ezisetshenziswa yibona zithengwa kubathengisi bemakethe abathembekile okuyikhwalithi eyengeziwe evivinywa ochwepheshe bemboni.Baphinde banikeze izici eziyingqayizivele emikhiqizweni yabo eyenziwe.Izici ezihlukile njengokuqedwa okuphezulu, ubukhulu obunembile, ukuqina okuhle nokulethwa ngesikhathi komkhiqizo ezinye zezinsizakalo.
