Insimbi ye-Corten B

Insimbi ye-Corten B
Ibanga lensimbi le-ASTM Corten B liyimikhiqizo egoqiwe eshisayo yezinsimbi zesakhiwo ezimweni zokulethwa kwezobuchwepheshe ezinokumelana nokugqwala okuthuthukisiwe komkhathi.Izinga lensimbi i-Corten B lihambisana nezinga le-ASTM elinamandla okukhiqiza angu-355MPa no-345MPa asekelwe ekugqimeni okuhlukile.
I-Corten B – insimbi ekwazi ukumelana nesimo sezulu ekulungele kangcono izakhiwo ezisindayo nezithwalayo.
Izinto ezisetshenziswayo zakha ungqimba lwazo oluvikelayo lapho zivezwe kuzinto zomkhathi. Empeleni, ungqimba olungaphezulu luyagqwala bese luvikela insimbi ngaphansi kwalo. Ukuqedwa kwemvelo ngokuvamile akudingi noma yiluphi uhlobo lokunakekelwa olufana nokudweba, okwenza okokusebenza kube ngenye indlela ebiza kakhulu kunezinye izinsimbi zesakhiwo.
Ukupenda nokunakekelwa kuyodingeka uma isakhiwo simanzi njalo njengoba ungqimba oluvikelayo lungeke lwakhiwe. Isibonelo esihle lapho isisekelo sesakhiwo sihlangana nomhlabathi noma sicwiliswe kancane.

I-ASTM Corten B steel Mechanical properties:
Ezingeni lokushisa legumbi lamapuleti ≥3mm ubukhulu (izibonelo zokuhlola ezishintshayo, ngokuya nge-EN 10002). Izimfuneko zamapuleti ashisayo aginqiwe ≤3mm ubukhulu ngokuya nge-EN 10025-5.

Amandla omthelela anqunywa kumasampula wokuhlola we-ISO-V longitudinal ezingeni lokushisa elingu-20°C njengesilinganiso sokuhlola okuthathu. Ngobukhulu bomkhiqizo ≥10mm inani eliyisilinganiso okungenani lingu-27 J. Ngobukhulu obuphakathi kuka-10mm no-6mm, inani elincane lomthelela liyancishiswa ngokulingana nobubanzi besifanekiso (ugqinsi lomkhiqizo).

I-Corten B Steel Delivery state

I-Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP), Electroslag Remelting Technical, ukuhlolwa kwe-HIC.
