Q355NH nyengo yachitsulo yokhala ndi zowotcherera zofananira

Chiyambi cha zitsulo zanyengo

Weathering steel ndi kalasi yachitsulo yokhala ndi kukana kwamphamvu kwambiri kwa mlengalenga, komwe ndikuwonjezera pang'ono Cr, Ni, Cu, P ndi zinthu zina ku chitsulo cha kaboni kuti apange wosanjikiza woteteza pamwamba pa matrix achitsulo, potero amachepetsa kupitirira. dzimbiri. Kukana kwa mlengalenga kwa chitsulo chosasunthika ndi 2 ~ 8 nthawi ya chitsulo cha kaboni wamba, ndi kukana dzimbiri, kukulitsa moyo wautumiki wa zigawo zomangira, kupatulira ndi kuchepetsa kumwa, ndi zina, zomwe zimagwiritsidwa ntchito kwambiri pamagalimoto, milatho, zotengera, nyumba, nsanja. ndi zina kwa nthawi yaitali kukhudzana ndi zitsulo mumlengalenga zitsulo.

Q355NH nyengo yachitsulo ntchito

Q355NH ndi ya welded weathering zitsulo

Atmospheric corrosion resistance index

Atmospheric corrosion resistance index (I) ndi index yofunikira yowunika kukana kwanyengo kwa zinthu, kukulira kwa index, kumapangitsa kuti chitsulo chisawonongeke ndi chitsulo, amakhulupirira kuti index (I) ≥ 6.0 chitsulo imakhala yabwinoko mumlengalenga. kukana dzimbiri.

The atmospheric corrosion resistance index (I) amawerengedwa motere:
I=26.01(%Cu)+3.88(%Ni)+1.20(%Cr)+1.49(%Si)+17.28(%P)-7.29(%Cu)(%Ni)-9.10(%Ni)(%P) )-33.39(%Cu)2
