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 cov tank steel thiab cov hlab ntsha. BBN steel muab carbon steel SA 283 Qib Chlau daim hlauSA 283 Qib C tiaj tus tuav, SA 283 Qib C lub kaum sab xis steel thiab SA283 Qib C lub kaum sab xis steel. Nrog rau kev xa khoom, EN 10204 3.1 lossis EN 10204 3.2 MTC kuj tau muab rau koj.
1. SA283 Qib C yog dab tsi?
SA283 Qib C yog qhov qis-carbon, dav dav- lub hom phiaj steel phaj hauv ASTM A283 tus qauv, feem ntau siv rau qis- kev siv cov qauv kev ntxhov siab xws li tso tsheb hlau luam, bins, thiab lub tsev thav duab uas yuav tsum tau siv vuam thiab sib sau.
2. Lub zog tawm ntawm SA283 Qib C yog dab tsi?
Qhov tsawg kawg nkaus tawm lub zog ntawm SA283 Qib C yog 30,000 psi (205 MPa), ua rau nws tsim nyog rau cov ntawv thov nrog cov qauv nruab nrab.
3. Qhov txawv ntawm SA283 Qib A, B, C, thiab D yog dab tsi?
Thawj qhov sib txawv yog nce zog: Qib A (24 ksi min yield), Qib B (27 ksi), Qib C (30 ksi), thiab Qib D (33 ksi). Cov qib siab dua muaj zog dua tab sis tsawg dua formability.
4. Puas yog SA283 Qib C weldable?
Yog lawm, SA283 Qib C muaj qhov zoo tshaj plaws weldability vim nws cov ntsiab lus carbon tsawg, ua rau nws tsim nyog rau feem ntau txoj kev vuam xws li SMAW, GMAW, thiab SAW yam tsis tas yuav tsum muaj cov txheej txheem nyuaj.
5. Dab tsi yog SA283 Qib C sib npaug hauv Tebchaws Europe?
Qhov sib npaug nyob sab Europe zoo tshaj plaws yog S235JR (EN 10025-2) raws li qhov sib piv cov khoom siv zog (~ 235 MPa nominal) thiab daim ntawv thov dav dav. Nco ntsoov tias S235JR muaj qhov yuav tsum tau muaj kev cuam tshuam toughness.
