Khoom Description
ASTM tus qauv tsimA 242hais txogCor-Ten A, uas muaj feem xyuam rau cov hlau phaj nrog tuab txog 12.7 hli, thaum cov qib ASTM tshiab, xws liA 588, sawv cevCor-Ten B, siv rau thicknesses ntau tshaj 12.7 hli.
Vuam ntawm Cor-Kaum hlau tuaj yeem ua tau los ntawm ntau txoj hauv kev, suav nrog cov ntaub thaiv npog roj welding, qhov chaw vuam, lossis submerged arc vuam, nrog rau kev xaiv tshwj xeeb nyob ntawm qhov tuab ntawm cov hlau. Xaiv txoj kev vuam tsim nyog yog qhov tseem ceeb los xyuas kom meej tias cov txheej txheem rusting txhim kho tsis tu ncua nrog rau cov qauv seem.
Txawm hais tias Corten A thiab Corten B muaj cov khoom zoo sib xws,Cor-Kaum A alloys feem ntau muaj cov ntsiab lus phosphorus ntau dua, uas muab kev txhim kho corrosion kuj.

Corten A thiab Corten B yog ob qho tib si huab cua cov qib steel tsim los tsim kev tiv thaiv xeb -zoo li patina, lawv txawv ntawm cov tshuaj muaj pes tsawg leeg, lub zog tensile, weldability, thiab kev siv tshwj xeeb.
Corten A tau txais kev pom zoo rau nws cov xeb zoo nkauj thiab kev siv vaj tse, thaum Corten B raug xaiv rau nws txoj kev txhim kho lub zog thiab kev tiv thaiv corrosion hauv cov qauv tsim.
