304 Stainless Hlau Round Bound muaj 18 - 20}} chromium thiab {{% npib tsib xee. Chromium Form Ib txheej Oxide passive txheej rau saum npoo ntawm cov hlau, uas muab cov corrosion tsis kam. Cov qib qib no yog tsim nyog rau ntau lub hom phiaj}}} lub hom phiaj tseem ceeb, xws li nyob rau sab hauv tsev cov khoom siv, thiab qee yam zaub mov {6} kev ua tshuab. Txawm li cas los xij, nyob rau hauv ib puag ncig nrog muaj cov kab chlorides, xws li nyob rau hauv ntug hiav txwv lossis hauv qee qhov chaw muaj tshuaj siv tshuaj lom neeg ntawm pitting ntawm pitector dhau sijhawm.
316L Stainless hlau puag ncig, ntawm qhov tod tes, muaj txhim kho corrosion tsis kam. Ntxiv nrog rau cov ntsiab lus chromium thiab npib tsib xee ({% chromium thiab {% npib tsib}}}% molybdenum. Lub molybdenum tau txhim kho cov hlau tiv thaiv mus rau chloride - induced corrosion. Qhov no ua rau 316L cov kev siv marine, xws li cov khoom lag luam nkoj, cov ntaub ntawv kiv cua, thiab dej hiav txwv- tuav cov khoom siv. Hauv cov nroj tsuag ua kev lom zem nyob qhov twg, 316L tseem muaj cov tshuaj uas zoo dua li nws tuaj yeem tiv taus ntau cov tshuaj uas dav dav. Tus "l" hauv 316L qhia tau cov ntsiab lus carbon tsawg, uas ntxiv txo qhov kev pheej hmoo ntawm qhov tsis txaus ntseeg thiab kev sib zog ntawm vuam thiab hauv qhov ntsuas kub thiab txias. Zuag qhia tag nrho, thaum 304 yog tus nqi -} Yuav tsum xaiv tau cov ntawv thov ntau ntxiv hauv ib puag ncig hnyav.
