1. Tus Qauv & Keeb Kwm
Corten a: Ua raws li ASTM A242 / A588 (American txheej txheem), lub ntiaj teb lees paub qib hluav taws xob nruj nrog nruj thoob ntiaj teb.
Q355NH: Ua raws GB / T 4171-2008 (Suav teb chaws), tsim rau cov haujlwm hauv tsev thiab cov haujlwm tsim kho nrog cov cheeb tsam raws li cov kev qhia tshwj xeeb.
2. Tshuaj lom neeg sib xyaw (ib qho tseem ceeb alloy)
Chromium (cr): Corten A muaj qhov dav / ntau dua (0.40-1.25%) {}} Enhances.
Phosphorus (p): Corten a (0.07-0.15%) thiab 0.07-0.12%) {6 {6 sai sai} sai sai pata tsim hauv Corten A.
Cov Kws Koom Tes Tswj: Corten A muaj cov kev txwv ntawm cov leej tub rog thiab cov pa oxygen (O), txo cov kev pheej hmoo hauv nroog. Q355NH ua rau ntau cov qib kev txhim kho kom haum dua.
3. Corrosion Kuj
Corten a: Zoo dua siab dua, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj mob hnyav (ntug dej hiav txwv, thaj chaw muaj thaj). Corrosion tus nqi yog 10-20% qis dua Q355Nh, nrog ib qho ruaj khov, tus kheej {{}}} rov qab txuas patina.
Q355NH: Txhim khu kev qha rau cov pej xeem sib txawv PATINA COV NTAUB NTAWV SLOWER (1.5-3 xyoos VS . 1}} - 2 xyoo rau corten a).
4. Cov Khoom Siv Neeg Kho Tshuab
Corten a: Lub zog tensile siab dua (485-655 MPa) thiab tawm lub zog (345 mpa me), haum rau kev siv kev ntxhov siab ntau.
Q355NH: Tawm lub zog (355 mpa min) phim nws lub npe kawm, nrog kev sib npaug ntawm-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}.
5. Daim ntawv thov tau
Corten a: Globally used for high-demand projects-bridges, coastal infrastructure, international architectural facades, and long-service-life (30+ years) structures. Nyiam rau kev xa tawm lossis cov phiaj xwm xav tau cov ntawv pov thawj thoob ntiaj teb.
Q355NH: Tseem ceeb hauv Suav cov haujlwm Suav teb chaws - txoj kev tiv thaiv loj, thiab luv - Lifestructure. Leverages lub zos mov txuas thiab tus nqi zoo.
