Puas yog stainless hlau tiag tiag stainless?
Stainless hlau (Stainless hlau) yog resistant rau huab cua, chav, dej thiab lwm yam tsis muaj zog corrosive media los yog stainless hlau. Nws cov corrosion kuj nyob ntawm cov hlau alloy muaj nyob hauv cov hlau. Feem ntau, cov ntsiab lus chromium ntau dua 12% thiab nws muaj Corrosive hlau hu ua stainless hlau. Chromium yog lub hauv paus ntsiab lus kom tau txais kev tiv thaiv corrosion ntawm stainless hlau. Thaum cov ntsiab lus chromium hauv cov hlau nce txog li 12%, chromium reacts nrog oxygen nyob rau hauv nruab nrab corrosive los tsim ib tug nyias oxide zaj duab xis (passivation zaj duab xis) nyob rau saum npoo ntawm cov hlau. ) Txhawm rau tiv thaiv corrosion ntxiv ntawm steel substrate. Thaum cov oxide zaj duab xis yog tsis tu ncua, cov pa atoms nyob rau hauv cov huab cua los yog kua yuav infiltrate mus ntxiv los yog cov hlau atoms nyob rau hauv cov hlau yuav txuas ntxiv mus cais tawm, tsim xoob hlau oxide, thiab stainless hlau nto yuav tsis tu ncua rusted.
Qhov loj ntawm stainless hlau lub peev xwm los tiv thaiv corrosion hloov nrog cov tshuaj muaj pes tsawg leeg ntawm cov hlau nws tus kheej, lub xeev ntawm kev tiv thaiv, cov kev mob ntawm kev siv, thiab hom ntawm ib puag ncig nruab nrab. Piv txwv li, 304 steel yeeb nkab muaj cov xeb zoo heev nyob rau hauv qhov chaw qhuav thiab huv si, tab sis nws yuav xeb sai sai thaum nws txav mus rau thaj tsam ntug dej hiav txwv hauv hiav txwv huab cua uas muaj cov ntsev ntau. zoo. Yog li ntawd, nws tsis yog txhua yam ntawm stainless hlau, uas tuaj yeem tiv taus corrosion thiab xeb nyob rau hauv ib puag ncig.
