Corten steel yog ib chav kawm ntawm cov hlau alloy, tom qab ob peb xyoos ntawm kev tawm sab nraum zoov tuaj yeem tsim cov txheej txheem xeb ntawm qhov chaw, yog li nws tsis tas yuav tsum tau pleev xim rau kev tiv thaiv. Feem ntau cov hlau tsis tshua muaj hlau zoo li xeb lossis xeb dhau sijhawm thaum raug dej los yog huab cua. Cov txheej xeb no ua ntxeem tau thiab ntog tawm ntawm cov hlau. Nws yog resistant rau corrosion los ntawm lwm yam tsawg alloy steels.
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 tsis yog xeb-tiv taus, tab sis thaum muaj hnub nyoog, nws muaj kev tiv thaiv corrosion siab (kwv yees li ob npaug ntawm cov hlau). Nyob rau hauv ntau daim ntawv thov ntawm weathering steel, txheej tiv thaiv xeb feem ntau tsim ib txwm tom qab 6-10 xyoo ntawm ntuj raug rau lub caij (nyob ntawm seb qhov kev raug mob). Tus nqi corrosion tsis tsawg kom txog rau thaum muaj peev xwm tiv thaiv cov xeb txheej tau pom, thiab qhov pib flash xeb yuav paug nws tus kheej nto thiab lwm qhov chaw nyob ze.
