Associated Tensile Strength: Qhov tsawg kawg nkaus tensile lub zog rau SA283 Qib C yog 55,000 psi (380 MPa).
Kev Siv Tsim: Cov kws tsim khoom siv lub zog qis kawg nkaus (30 ksi / 205 MPa) rau kev suav tsim kev nyab xeeb. Lub zog tawm los tiag tiag los ntawm daim ntawv pov thawj zeb xeem feem ntau yuav siab dua.
Daim ntawv thov Scope: Lub zog nruab nrab no, ua ke nrog cov weldability zoo thiab formability vim muaj cov pa roj carbon tsawg, ua rau SA283 Qib C haum rau kev tsim khoom, cov tso tsheb hlau luam, cov kav dej, thiab cov khoom siv teeb pom kev zoo -tab sis tsis yog rau cov hlab ntsha siab lossis siab - kev siv kev ntxhov siab.
Nyob rau hauv cov ntsiab lus, 30,000 psi (205 MPa) yog qhov guaranteed yam tsawg kawg nkaus yield zog koj yuav qhia kom meej rau tsim thaum siv SA283 Qib C steel phaj.
Cov yam ntxwv ntawm carbon steel SA 283 Qib C:
| Yield zog (Mpa) | Tensile zog (Mpa) | Elongation Ntau dua lossis sib npaug ,% |
| 205 | 380-515 | 22 |
Kev siv feem ntau ntawm cov pa roj carbon steel SA 283 Qib C yog nyob rau hauv kev lag luam hnyav thiab cov nroj tsuag roj rau tsim steel tanks thiab cov hlab ntsha. BBN steel muab cov pa roj carbon steel SA 283 Qib C steel daim hlau, SA 283 Qib C tiaj tus tuav, SA 283 Qib C lub kaum sab xis steel thiab SA283 Qib C lub kaum ntse ntse. Nrog rau kev xa khoom, EN 10204 3.1 lossis EN 10204 3.2 MTC kuj tau muab rau koj.
