Dab tsi yog {18-10} stainless hlau?

18-10}} Tus hlau Stainless yog ib hom ntawm cov hlau tsis muaj zog nrog "txog 18%}}}" raws li cov tseem ceeb. Nws yog ib qho kev hloov kho tshiab ntawm cov classic {3}} back stainless hlau (xws li 304 stainless cov ntsiab lus ntawm {}}. 5%), nrog cov ntsiab lus tsib xee. Nws tau zoo dua corrosion tsis kam thiab cov qauv kev ruaj ntseg, thiab muaj feem ntau siv rau kev ua kom xeb thiab muaj kev nyab xeeb, khoom siv kho mob, khoom siv ua haujlwm, thiab lwm yam.
