I-Q355NH yensimbi yesimo sezulu enezinto ezisebenzisekayo zokushisela ezifanayo

Isingeniso sensimbi yesimo sezulu

I-Weathering steel iyizinga lensimbi elinokumelana nokugqwala okuhle kakhulu komkhathi, okungeza inani elincane le-Cr, i-Ni, i-Cu, i-P nezinye izakhi ensimbi ye-carbon ukuze kwakhe ungqimba oluvikelayo ebusweni be-matrix yensimbi, ngaleyo ndlela wehlise ijubane ngokuqhubekayo. ukugqwala. Ukumelana nokugqwala komkhathi kwensimbi yesimo sezulu kuyizikhathi ezi-2 ~ 8 kune-carbon steel ejwayelekile, enokumelana nokugqwala, inweba impilo yesevisi yezingxenye zesakhiwo, ukunciphisa nokunciphisa ukusetshenziswa, njll., esetshenziswa kakhulu ezimotweni, amabhuloho, iziqukathi, izakhiwo, imibhoshongo. nokunye ukuchayeka isikhathi eside ezakhiweni zensimbi zasemkhathini.

Ukusebenza kwensimbi ye-Q355NH sezulu

I-Q355NH ingeyensimbi yesimo sezulu esishiselwe

Inkomba ye-Atmospheric corrosion resistance

Inkomba yokumelana nokugqwala kwe-atmospheric (I) iyinkomba ebalulekile yokuhlola ukumelana nesimo sezulu sezinto zokwakha, inkomba enkulu, ingcono ukumelana nokugqwala kwensimbi komoya, ngokuvamile kukholelwa ukuthi lapho inkomba (I) ≥ 6.0 insimbi inomkhathi ongcono. ukumelana nokugqwala.

I-atmospheric corrosion resistance index (I) ibalwa kanje:
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

I-Fillet Welding (ngaphambi kokususwa kwe-slag)

I-Fillet Welding (ngemuva kokususwa kwe-slag)

Njengenjwayelo, siyaqhubeka nokukunikeza izinto ezisetshenziswayo zokushisela eziseqophelweni eliphezulu namasevisi!
