Nws tsim ib txheej oxide passive rau ntawm qhov chaw, hu ua chromium oxide, uas ua raws li kev tiv thaiv kev tiv thaiv corrosion.
Cov nickel concentration yog li ntawm 8 mus rau 10.5%, ua lub luag haujlwm tseem ceeb hauv kev ua kom cov hlau tsis kam tiv thaiv corrosion thiab nws lub peev xwm los tiv thaiv qhov dav dav ntawm qhov kub thiab txias. Cov ntsiab lus nickel no tseem qhia txog qib tseem ceeb ntawm ductility thiab toughness rau cov hlau, ua rau nws tsim nyog rau ntau hom kev tsim khoom. Tshaj li hlau, chromium, thiab npib tsib xee, 304 stainless hlau suav nrog cov lej ntawm carbon, manganese, silicon, thiab lwm yam. Cov ntsiab lus carbon yog khaws cia qis dua 0.08%, ua kom cov hlau tseem tsis muaj zog thiab khaws nws cov yam ntxwv tiv thaiv corrosion. Manganese pab txhim kho lub zog thiab kev ua haujlwm ntawm cov hlau, thaum silicon pab txhawb kom muaj zog tiv thaiv kev ntsuas ntawm qhov kub siab.
