Cov txiaj ntsig
- Lub zog thiab Durability: Carbon steel daim hlau paub txog lawv lub zog tensile siab thiab muaj peev xwm tiv taus cov khoom hnyav.
- Tus nqi -Kev ua tau zoo: Lawv feem ntau pheej yig dua piv rau lwm hom hlau, ua rau lawv xaiv rau ntau yam haujlwm.
- Weldability: Ntau cov pa roj carbon steel tuaj yeem yooj yim welded, tso cai rau ntau yam kev tsim kho thiab kev xaiv fabrication.
Cov pa roj carbon steel phaj muaj nyob rau hauv ntau qib, categorized raws li cov ntsiab lus carbon thiab lub zog.
Cov phaj no raug cais raws li qis, nruab nrab, thiab siab carbon steel. Ua kom cov pa roj carbon ntau ntxiv ua rau lub phaj ruaj khov thiab lub zog. Tsis tas li ntawd, muaj subcategories raws li thickness, kev siv, thiab kev tsim khoom. Feem ntau, cov pa roj carbon steel phaj muaj qhov tuab ntawm 0.4 hli txog 80 hli, nrog qhov dav sib txawv ntawm 1,000 hli txog 45,000 hli, thiab qhov ntev tuaj yeem ncav cuag 18 meters. Txawm li cas los xij, qhov ntev tuaj yeem hloov kho kom tau raws li kev thov tshwj xeeb. Tsis tas li ntawd, cov phiaj no tuaj yeem siv los ua cov khoom txias -rolled steel coils.
muab tso rau hauv ntau yam kev siv. Ib qho tuaj yeem ua kom txias dov steel coils los ntawm lawv.
