Vim li cas Stainless Hlau Hlau Rope Resistant rau Corrosion?

When stainless steel contacts oxygen, a thin, dense and adherent passive chromium oxide film automatically forms on the surface. Cov txheej tiv thaiv no nruj nreem npog cov hlau substrate, cais cov pa oxygen, noo noo, ntsev ions thiab corrosive media. Qhov tseem ceeb, cov yeeb yaj kiab tsis muaj zog ua rau tus kheej - kho muaj peev xwm. Yog tias qhov khawb me me ua rau lub ntsej muag puas tsuaj, cov yeeb yaj kiab tiv thaiv tshiab yuav rov tsim dua sai sai hauv cov pa oxygen- ib puag ncig nplua nuj los tiv thaiv kev xeb tsis tu ncua.

Chromium (Cr)

Lub hauv paus tseem ceeb rau kev tiv thaiv -corrosion. Stainless hlau feem ntau muaj tsawg kawg yog 10.5% chromium los tsim cov yeeb yaj kiab ruaj khov. Cov ntsiab lus chromium siab dua muab cov xeb zoo dua.

Nickel (Ni)

Txhim kho cov khoom toughness thiab stabilizes metallographic qauv. Nws ntxiv dag zog rau cov txheej txheem passive ua haujlwm nyob rau hauv qis kub thiab acidic tej yam kev mob.

Molybdenum (hli)

Zoo tiv taus pitting thiab crevice corrosion tshwm sim los ntawm chloride ions xws li dej hiav txwv ntsev tsuag. Qhov no yog vim li cas molybdenum- cov qhab nia ua tau zoo dua hauv cov xwm txheej hauv hiav txwv.

Nantong Solite Rope Co., Ltd feem ntau muab ob qib tseem ceeb rau cov haujlwm thoob ntiaj teb:
304 Stainless Hlau Hlau Rope
Tus nqi -kev xaiv zoo rau dej tshiab, huab cua ib puag ncig, khoom noj khoom haus thiab cov chaw sab nraum zoov. Haum rau cov uas tsis yog - dej hiav txwv corrosive.
316 Stainless Hlau Hlau Rope
Ntxiv molybdenum tivthaiv. Kev tiv thaiv zoo tiv thaiv dej ntsev, ntsev tsuag thiab me ntsis acid. Qhov kev xaiv zoo tshaj plaws rau kev sib tw offshore, yacht fittings, kev tsim kho ntug hiav txwv thiab cov khoom siv marine.

1. Cov zaj duab xis passive cia siab rau oxygen. Stainless hlau hlau hlua tseem muaj kev pheej hmoo ntawm kev xeb nyob rau hauv ntev - lub sij hawm kaw tag nrho, oxygen - ib puag ncig tsis txaus.
2. Tsis txhob ntev - kev sib cuag nrog cov kua qaub uas muaj zog, muaj zog alkalis thiab cov ntsiab lus chloride. Stainless hlau tsis yog corrosion tag nrho - pov thawj nyob rau hauv cov tshuaj phem heev.
3. Cov av hauv av, sediment thiab marine attachments yuav tsum tau ntxuav tsis tu ncua kom muaj kev ncaj ncees ntawm cov yeeb yaj kiab passive thiab txuas ntxiv lub neej kev pab cuam.
4. Tsis txhob cuam tshuam stainless hlau hlua hlua nrog galvanized carbon steel hlau hlua. galvanized hlua cia siab rau kev txi zinc txheej; Thaum cov zinc txheej hnav tawm, cov hlau substrate yuav xeb sai sai.

Cias muab, stainless hlau xaim hlua tau txais kev tiv thaiv corrosion los ntawm tus kheej - kho chromium oxide passive zaj duab xis tsim los ntawm chromium alloying. Thaum xaiv cov khoom, cov neeg yuav khoom yuav tsum paub qhov txawv ntawm 304 thiab 316 qib raws li qhov chaw ua haujlwm.Nantong Solite hlua Co., Ltdmuab customized stainless hlau xaim hlua ntawm ntau yam kev tsim kho thiab txoj kab uas hla kom tau raws li ntau haiv neeg los tiv thaiv- corrosion lifting thiab tensioning xav tau thoob ntiaj teb.
