Corten a thiab Q355Snh yog ob qho hluav taws kub nrog cov zoo corrosion tsis kam, thiab lawv txoj kev tawm tsam corrosion zoo sib xws. Feem ntau, corten A yuav muaj me ntsis zoo corrosion tsis kam nyob rau qee qhov chaw ib puag ncig.
Corten A yog qhov siab - muaj zog tsawg {{}} Alloy} Alloy} Almoal Txheej Txheem Hlau uas tau ua tau raws li ATM A242 / ASTM A242 / ASTM A588 tus qauv. Q355NH yog cov huab cua ua hluav taws xob hauv Suav teb lub teb chaws qauv GB / T 4171, thiab nws yog suav hais tias yog sib npaug rau Corten A. Ob qho ob muaj zoo sib xws unloying tshuab. Nkawd ob leeg muaj cov khoom siv xws li tooj liab (Cu), chromium (thiab menyuam yaus (NI)
Txawm li cas los xij, cov phosphorus (p) cov ntsiab lus hauv corten a yog 0.07%- 0.15%. Qhov no tseem ceeb phosphorus cov ntsiab lus pab txhawb kom txhawb nqa kev tsim cov txheej txheem tiv thaiv oxide thiab txhim kho corrosion tsis kam. Cov ntsiab lus phosphorus hauv Q355Snh tsawg dua lossis sib npaug rau 0.030%, uas yog qhov qis dua uas hauv Q355Nh yog 0.40% {%. Cov kev txwv ntawm cov ntsiab lus chromium hauv corten a yog siab dua, uas kuj yuav ua rau nws corrosion tiv taus me ntsis zoo dua.
