Kubhekwa "njengento ephilayo" ngenxa yenqubo yayo eyingqayizivele yokuvuthwa/yokuxutshwa kwe-oxidation. Izithunzi namathoni ashintsha ngokuhamba kwesikhathi, kuye ngesimo sento, lapho ifakwe khona, kanye nomjikelezo wesimo sezulu umkhiqizo osudlulile kuwo. Isikhathi esizinzile ukusuka ku-oxidation kuya ekuvuthweni ngokuvamile siyizinyanga eziyi-12-18. Umthelela wendawo wokugqwala ngeke ungene kokubalulekile, ukuze insimbi yakhe isendlalelo semvelo sokuvikela ukugqwala.

Insimbi ye-Corten iyinsimbi ye-alloy equkethe izinto ezintathu ezibalulekile ze-nickel, ithusi ne-chromium, futhi ngokuvamile inokuqukethwe kwekhabhoni okungaphansi kuka-0.3% ngesisindo. Umbala wawo osawolintshi olula ngokuyinhloko ngenxa yokuqukethwe kwethusi, okuthi ngokuhamba kwesikhathi kuhlanganiswe ungqimba oluvikelayo oluyithusi oluluhlaza ukuvimbela ukugqwala.

Ukuthandwa kuka-Corten kungabangelwa amandla ayo, ukuqina, ukusebenza kahle, nokukhanga kobuhle.I-Corten Steel inezinzuzo eziningi, kuhlanganise nokugcinwa nokuphila kwesevisi. Ngaphezu kwamandla ayo aphezulu, insimbi ye-corten iyinsimbi yokulungisa ephansi kakhulu. Ngoba i-Coreten Imelana nemiphumela elonakalisayo yemvula, iqhwa, iqhwa, inkungu, nezinye izimo zezulu ngokwakha i-oxidizing coating onsundu ngokumnyama, ngaleyo ndlela ivimbele ukungena okujulile futhi iqede isidingo sikapende nokugqwala okumba eqolo phakathi neminyaka. Kalula nje, ukugqwala kwensimbi, nokugqwala kwakha isivikelo

I-Corten steel imelana nemiphumela elimazayo yemvula, iqhwa, iqhwa, inkungu, nezinye izimo zezulu ngokwakha i-oxidizing ensundu emnyama endaweni yensimbi. I-Corten steel iwuhlobo lwensimbi ene-phosphorus, ithusi, i-chromium, i-nickel ne-molybdenum eyengeziwe. Lawa ma-alloys athuthukisa ukumelana nokugqwala kwe-atmospheric of weathering steel ngokwenza ungqimba oluyisivikelo ebusweni bayo.

Corten steel ngeke ukugqwala. Ngenxa yokwakheka kwamakhemikhali, ikhombisa ukumelana okuphezulu nokugqwala komkhathi kunensimbi ethambile. Ingaphezulu lensimbi lizogqwala, kwenze ungqimba oluvikelayo esilubiza ngokuthi "patina."

I-Corten steel iwumndeni wezinsimbi ezithambile eziqukethe izakhi ezengeziwe ze-alloying ezixutshwe ne-carbon ne-athomu yensimbi. Kodwa lezi zakhi ze-alloying zinikeza insimbi yesimo sezulu amandla angcono kanye nokumelana nokugqwala okuphezulu kunamamaki ensimbi athambile. Ngakho-ke, insimbi ye-corten ivame ukusetshenziswa emisebenzini yangaphandle noma ezindaweni lapho insimbi evamile ijwayele ukugqwala.
