Q355NH weathering simbi ine matching welding consumables

Nhanganyaya kune weathering simbi

Weathering simbi igiredhi resimbi ine yakanakisa mumhepo inodzivirira kukora, kuri kuwedzera hushoma hweCr, Ni, Cu, P uye zvimwe zvinhu kune kabhoni simbi kuumba inodzivirira layer pamusoro pesimbi matrix, nekudaro ichidzikira mberi. ngura.Kupokana kwemuchadenga kusimba kwesimbi inonaya inosvika 2 ~ 8 nguva yeyakajairwa kabhoni simbi, ine ngura kuramba, ichiwedzera hupenyu hwesevhisi yezvikamu zvechimiro, kuonda uye kuderedza kushandiswa, nezvimwewo, inonyanya kushandiswa mumotokari, mabhiriji, midziyo, zvivakwa, shongwe. uye kumwe kuratidzwa kwenguva refu kune zvivakwa zvesimbi zvemuchadenga.

Q355NH mamiriro ekunze esimbi kuita

Q355NH ndeye welded weathering simbi

Atmospheric corrosion resistance index

Atmospheric corrosion resistance index (I) indekisi yakakosha yekuongorora kuramba kwemamiriro ekunze kwezvinhu, iyo indekisi yakakura, inova nani kupikisa kwemhepo yesimbi, zvinotendwa kuti kana index (I) ≥ 6.0 simbi ine zviri nani mumhepo. corrosion resistance.

Iyo atmospheric corrosion resistance index (I) inoverengwa sezvinotevera:
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
