Nws raug suav hais tias yog ib qho khoom siv "nyob" vim nws qhov tshwj xeeb maturation / oxidation txheej txheem. Duab ntxoov ntxoo thiab tones hloov lub sij hawm, nyob ntawm seb cov duab ntawm cov khoom, qhov twg nws yog ntsia, thiab lub voj voog huab cua ntawm cov khoom tau dhau mus. Lub sijhawm ruaj khov ntawm oxidation mus rau kev loj hlob yog feem ntau 12-18 lub hlis. Cov nyhuv corrosion hauv zos yuav tsis nkag mus rau cov khoom siv, yog li cov hlau tsim cov txheej txheem tiv thaiv corrosion.

Corten steel yog cov hlau alloy uas muaj peb lub ntsiab lus nickel, tooj liab thiab chromium, thiab feem ntau muaj cov ntsiab lus carbon tsawg dua 0.3% los ntawm qhov hnyav. Nws cov xim txiv kab ntxwv sib zog yog feem ntau vim yog cov ntsiab lus tooj liab, uas dhau sij hawm yog them nrog tooj liab-ntsuab tiv thaiv txheej los tiv thaiv corrosion.

Corten cov koob npe tuaj yeem raug ntaus nqi rau nws lub zog, ua haujlwm ntev, kev ua tau zoo, thiab kev zoo nkauj zoo nkauj. Ntxiv nrog rau nws lub zog siab, corten steel yog ib qho kev kho qis heev. Vim tias Coreten Tiv thaiv cov corrosive los nag, daus, dej khov, pos huab, thiab lwm yam huab cua los ntawm kev tsim cov xim av tsaus nti oxidizing txheej ntawm cov hlau, yog li inhibiting kev nkag mus tob dua thiab tshem tawm cov kev xav tau ntawm cov xim thiab kim xeb txij nkawm ntau xyoo. Cias muab tso, steel xeb, thiab xeb ua ib qho kev tiv thaiv txheej

Corten steel tiv thaiv cov corrosive los nag, daus, dej khov, pos huab, thiab lwm yam huab cua los ntawm kev tsim cov xim av tsaus nti oxidizing txheej ntawm cov hlau. Corten steel yog ib hom hlau nrog ntxiv phosphorus, tooj liab, chromium, nickel thiab molybdenum. Cov alloys no txhim kho atmospheric corrosion kuj ntawm weathering steel los ntawm kev tsim ib txheej tiv thaiv ntawm nws nto.

Corten steel yuav tsis xeb. Vim nws cov tshuaj lom neeg muaj pes tsawg leeg, nws muaj kev tiv thaiv siab dua rau atmospheric corrosion dua li cov hlau me me. Qhov saum npoo ntawm cov hlau yuav xeb, tsim cov txheej txheem tiv thaiv uas peb hu ua "patina."

Corten steel yog ib tsev neeg ntawm cov hlau me me uas muaj cov alloying ntxiv nrog cov pa roj carbon thiab hlau atoms. Tab sis cov alloying ntsiab lus muab weathering steel zoo zog thiab siab corrosion kuj dua li cov qib me me steel. Yog li ntawd, corten steel feem ntau yog siv rau sab nraum zoov daim ntaub ntawv los yog nyob rau hauv ib puag ncig uas zoo tib yam steel nyhav rau xeb.
