Corten Steel ASTM A242 Pipes feem ntau siv hauv kev tsim kho thiab kev siv sab nraum zoov qhov twg cov kav dej raug rau huab cua hnyav. Lawv kuj tau siv rau hauv cov txuas hniav, cov tsev & lwm cov qauv uas lawv cov khoom muaj zog thiab corrosion kuj yuav tsum tau. Tsis tas li ntawd, lawv tuaj yeem siv rau kev kho kom zoo nkauj vim lawv cov xeb tshwj xeeb zoo li cov tsos.
ASTM A242 Corten Steel Pipes yog qib hlau alloy ua los ntawm hlau, carbon, thiab lwm yam khoom xws li molybdenum, manganese, chromium, npib tsib xee, tooj liab, thiab vanadium. Feem ntau, cov kav dej no muaj nyob nruab nrab ntawm 0.25% thiab 0.50% cov ntsiab lus carbon, thiab cov seem yog cov khoom siv alloyed xws li cov uas tau hais los saum no. Qhov sib xyaw ntawm cov hlau alloy tuaj yeem sib txawv nyob ntawm qhov xav tau ntawm cov yeeb nkab nws tus kheej. Muaj cov qib sib txawv xws li ASTM A423 Qib 1 Pipes, ASTM A709-50W Pipes, thiab lwm yam.
