Dab tsi yog cov khoom ntawm A283 Welded yeeb nkab?
ASTM A283 Welded Yeeb Rau Tsawg Carbon Hlau Welded Steel Yeeb Nkab, feem ntau yog siv rau kev thauj mus los nruab nrab thiab kev lag luam tsis tshua muaj siab. Nws cov khoom muaj xws li:
Hom theem pib: carbon qauv hlau (tsis-alloy hlau), tsim los ntawm kub-rolled steel phaj raws li cov khoom siv los ntawm cov txheej txheem yeeb nkab welded;
Corrosion Kuj: ib txwm tiv taus atmospheric corrosion, tab sis yuav tsum tau muaj kev tiv thaiv txheej txheem siv hauv cov chaw noo noo;
Cov txheej txheem hloov tau: Weldability zoo heev thiab txias dabtsi rau cov qauv no haum, haum rau cov qauv kev txhawb nqa thiab kev tso tsheb hlau luam.
Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm A283 Welded yeeb nkab (noj G.C qib ua piv txwv)
| Muaj pes tsawg | Cov ntsiab lus ntau | Tswj Yuav Tsum Tau |
|---|---|---|
| C | Tsawg dua los yog sib npaug rau 0.29% | Tsawg Carbon Ua Kom Muaj Kev Siv Vuam Sib Tw |
| Mn | 0.85-1.20% | Txhim kho kev nruj thiab lub zog |
