Selelekela sa tšepe ea boemo ba leholimo
Weathering steel ke boemo ba tšepe bo nang le khanyetso e ntle ea kutu ea sepakapaka, e leng ho eketsa palo e nyane ea Cr, Ni, Cu, P le likarolo tse ling ho tšepe ea carbon ho theha lesela le sireletsang holim'a matrix a tšepe, ka hona ho fokotsa lebelo le ho feta. bofokoli.Khanyetso ea kutu ea sepakapaka ea tšepe ea boemo ba leholimo ke makhetlo a 2 ~ 8 ea tšepe e tloaelehileng ea k'habone, e hanyetsanang le mafome, e lelefatsa bophelo ba ts'ebeletso ea likarolo tsa meralo, ho fokotsa le ho fokotsa tšebeliso, joalo-joalo, e sebelisoang haholo likoloing, marokho, lijana, meaho, litora. le ho pepeseha tse ling tsa nako e telele ho meaho ea tšepe ea sepakapaka.

Atmospheric corrosion resistance index
Atmospheric corrosion resistance index (I) ke index ea bohlokoa ea ho lekola boemo ba leholimo ba thepa, ha index e kholoanyane, e ntlafatsa ho hanyetsa kutu ea sepakapaka ea tšepe, hangata ho lumeloa hore ha index (I) ≥ 6.0 tšepe e na le sepakapaka se betere. khanyetso ea kutu.
The atmospheric corrosion resistance index (I) e baloa ka tsela e latelang:
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
