Corten simbi isimbi yealloy. Mushure memakore akati wandei ekuratidzwa kwekunze, huturu hwakakora hunogona kuumbwa pamusoro, saka haidi kupendwa kuti dzidzivirire. Zita rinonyanya kuzivikanwa resimbi yemamiriro ekunze ndi "cor-ten", inova chidimbu che "corrosion resistance" uye "tensile simba", saka inowanzonzi "Corten steel" muchiRungu. Kusiyana nesimbi isina tsvina, inogona kunge isina ngura zvachose, simbi inonaya inongowedzera oxidize pamusoro pepamusoro uye haipindi mukati memukati, saka ine yakakwirira anti-corrosion properties.
Corten simbi inoonekwa se "mhenyu" zvinhu nekuda kweiyo unipue maturation /oxidation process. Mvuri uye toni zvichachinja nekufamba kwenguva, zvichienderana nechimiro chechinhu, kwachaiswa, uye kutenderera kwemamiriro ekunze chigadzirwa chinopinda. Nguva yakagadzika kubva pa oxidation kusvika pakukura kazhinji mwedzi 12-18. Iyo ngura yemunharaunda haipindi mukati mechinhu, kuitira kuti simbi inongogadzira danda rekudzivirira kuti isaita ngura.
Corten simbi haigoni kuita ngura. Nekuda kwekuumbwa kwayo kwekemikari, inoratidzira kupikisa kwakakwirira kumhepo yemhepo kupfuura simbi yakapfava. Iyo pamusoro pesimbi ichaita ngura, ichigadzira chidziviriro chekudzivirira chatinoti "patina."
Iyo corrosion inhibition effect yeverdigris inogadzirwa neiyo chaiyo kugovera uye kusungirirwa kweiyo alloying zvinhu. Iyi yekudzivirira inochengetedzwa sezvo patina inoramba ichikura uye ichivandudza kana ichinge yasangana nemamiriro ekunze. Saka inogona kushandiswa kwenguva yakareba pasina kukuvara nyore.
