Muri Reta zunzubumwe zamerika mu myaka ya za 1930, abakora amakara yamakara babonye ko ibyuma bimwe na bimwe bivangwa nicyuma byateje ingese ingese, iyo ihuye nibi bintu, itari kubora ibyuma, ahubwo izayirinda.
Ikiramba kiramba, cyubutaka, orange-umukara sheen yiyi mavuta yahise imenyekana cyane mububatsi kandi iracyakomeza kugeza na nubu.
Icyuma cya Corten ni uruvange rwibyuma hamwe nuruvange rutandukana ukurikije urwego rwibyuma bya corten. Nicyuma cyongewemo fosifore, umuringa, chromium na nikel-molybdenum. Mbere yo guhura nibintu hejuru yacyo yijimye, yijimye yijimye ishobora kwerekana ibicuruzwa bitatanzwe, ariko igihe nikigera bizatera patina ibyo.
Nkuko byavuzwe haruguru, ibyuma bya Corten nicyuma cyihanganira ikirere gishobora nanone kwitwa 'Atmospheric Corrosion Resistant Steel', kandi ni ibintu bivangavanze byumuringa na chromium bitanga uru rwego rwo kurwanya ikirere.
Ibyuma bya Corten ntibikwiye gusa muburyo bwiza, ariko kandi birakenewe mubikorwa: biramba, birinda ikirere kandi birwanya ubushyuhe. Urusenda rwicyuma rushobora gutwika, kunywa itabi, no kuryoha ibiryo byawe kuri 1000 ° F (559 ° C). Ubu bushyuhe buzahita bwikubita kuri stake no gufunga muri gravy.Kandi nibikorwa byayo kandi biramba ntakibazo kirimo.Kubera ubushyuhe bwayo bwinshi, ibyuma byikirere birashobora gukoreshwa mubitereko byo hanze cyangwa amashyiga.
