Cov qauv tsim ntawm stainless hlau

 

Kev tiv thaiv corrosion ntawm stainless hlau txo nrog kev nce ntawm cov ntsiab lus carbon. Yog li ntawd, cov ntsiab lus carbon ntawm feem ntau stainless hlau yog tsawg, tsis pub tshaj 1.2% feem ntau. Lub ωc (cov ntsiab lus carbon) ntawm qee cov hlau tseem qis dua 0.03% (xws li 00Cr12). Lub ntsiab alloying nyob rau hauv stainless hlau yog Cr (chromium). Tsuas yog thaum cov ntsiab lus Cr ncav cuag ib qho nqi, cov hlau yog corrosion-resistant. Yog li, Cr (chromium) cov ntsiab lus ntawm stainless hlau feem ntau yog tsawg kawg yog 10.5%. Stainless hlau kuj muaj Ni, Ti, Mn, N, Nb, Mo, Si, Cu thiab lwm yam.
