Cov pa roj carbon steel yeeb nkab yog tsim los ntawm kev tho cov hlau ingots lossis cov hlau puag ncig rau hauv cov raj ntxhib, thiab tom qab ntawd kub - dov, txias - dov lossis txias - kos. Feem ntau, carbon steel kav yog tsim los ntawm kub- dov los yog txias - dov siab - zoo carbon structural steel xws li 10, 20, 30, 35, 45, tsis tshua muaj alloy structural steel xws li 16Mn, 5MnV los yog alloy steel xws li 40Cr, 30S, Mn4, Cr. Seamless kav ua los ntawm cov pa roj carbon tsawg xws li 10 thiab 20 feem ntau yog siv rau cov kav dej thauj mus los. Cov kav dej tsis sib haum ua los ntawm cov pa roj carbon nruab nrab xws li 45 thiab 40Cr yog siv los tsim cov khoom siv kho tshuab, xws li thauj khoom -cov kabmob ntawm cov tsheb thiab tsheb laij teb. [1] Carbon steel kav muaj txoj haujlwm tseem ceeb hauv kuv lub teb chaws cov yeeb nkab steel kev lag luam.
CO2 cov kav dej thauj mus los tsuas yog siv siab -frequency resistance welded kav (HFW), thiab qib steel feem ntau yog X65-X80. Thaum lub Tsib Hlis 2023, kuv lub teb chaws tau ua thawj zaug tag nrho -qhov loj me ntawm cov raj xa dej CO2 hauv Suav teb. Lub raj xa dej yog HFW welded yeeb nkab nrog qhov tshwj xeeb ntawm Φ323.9 hli thiab X65 steel qib. Hydrogen cov kav dej thauj mus los feem ntau yog ua los ntawm qib qis - qib carbon steel thiab cov hlau tsis tshua muaj hlau welded lossis seamless kav.
