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.
Nws thawj zaug tshwm sim nyob rau hauv 1930s thiab tau siv tsuas yog rau kev tsheb ciav hlau cov tsheb thauj neeg. Weathering steel (lub npe nrov rau Corten, thiab weathering steel) tseem siv dav rau cov thawv vim nws qhov toughness. Civil engineering daim ntaub ntawv uas tshwm sim tom qab thaum ntxov 1960s coj ncaj qha mus rau Corten qhov txhim kho corrosion kuj, thiab nws tsis siv sij hawm ntev rau kev siv hauv kev tsim kho kom pom tseeb.
Cov khoom ntawm Corten tshwm sim los ntawm kev ua tib zoo saib xyuas cov ntsiab lus alloying ntxiv rau cov hlau thaum tsim khoom. Tag nrho cov hlau tsim los ntawm txoj hauv kev tseem ceeb (hauv lwm lo lus, los ntawm cov hlau ore ntau dua li cov khoom seem) yog tsim thaum hlau smelted nyob rau hauv lub qhov cub tawg thiab txo qis hauv lub converter. Cov ntsiab lus ntawm cov pa roj carbon monoxide raug txo qis thiab qhov tshwm sim ntawm cov hlau (tam sim no steel) yog nkig tsawg thiab muaj peev xwm thauj khoom ntau dua li ua ntej.
Feem ntau cov hlau tsis tshua muaj hlau xeb vim muaj huab cua thiab noo noo. Qhov no tshwm sim sai npaum li cas yuav nyob ntawm seb ntau npaum li cas noo noo, oxygen thiab atmospheric pollutants nws los rau hauv qhov chaw. Nrog rau huab cua steel, raws li cov txheej txheem nce mus, cov xeb txheej tsim ib qho kev thaiv uas tiv thaiv cov dej paug, noo noo thiab oxygen. Qhov no tseem yuav pab kom ncua cov txheej txheem rusting rau qee qhov. Cov txheej rusted no tseem yuav cais tawm ntawm cov hlau tom qab ib ntus. Raws li koj tuaj yeem nkag siab, qhov no yuav yog lub voj voog rov ua dua.
