Q355NH nyengo yachitsulo yokhala ndi zida zofananira zowotcherera

Chiyambi cha zitsulo zanyengo

Weathering steel ndi kalasi yachitsulo yokhala ndi kukana kwamphamvu 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.Kulimbana ndi dzimbiri mumlengalenga wa chitsulo weathering ndi 2 ~ 8 nthawi wamba mpweya zitsulo, ndi dzimbiri kukana, kuwonjezera moyo utumiki wa zigawo structural, kupatulira ndi kuchepetsa kumwa, etc., makamaka ntchito magalimoto, milatho, muli, nyumba, nsanja. ndi zina kwa nthawi yaitali kukhudzana ndi zitsulo mumlengalenga zitsulo.

Kuchita kwachitsulo kwa Q355NH

Q355NH ndi ya welded weathering zitsulo

Atmospheric corrosion resistance index

Atmospheric corrosion resistance index (I) ndi index yofunikira yowunikira 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
