Cov khoom siv rau ASTM A671 CC60 steel kav tsim siv ob -submerged arc vuam yog carbon steel phaj. Nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab yuav tsum ua raws li cov kev qhia tshwj xeeb hauv ASTM cov qauv. Cov khoom siv ntawm qib CC60 yog sib npaug ntawm ASTM A516 qib 60, khav theeb cov khoom siv zoo heev nrog rau lub zog tensile, lub zog tawm los, thiab elongation. Cov khoom no xyuas kom meej tias cov kav dej tuaj yeem tiv taus lub siab sab hauv thiab muaj qhov zoo ductility.
Tshwj xeeb, qhov tsawg kawg nkaus tawm lub zog ntawm qib CC60 steel kav yog kwv yees li 414 MPa (raws li kev hloov pauv ntawm 60 ksi, qhov twg 1 ksi=6.895 MPa). Qhov no ua rau lawv haum rau kev khiav hauj lwm tej yam kev mob uas muaj tej theem ntawm siab thiab kub. Tsis tas li ntawd, cov kav hlau no muaj kev tiv thaiv corrosion zoo thiab tsis tshua muaj -kub toughness, ua rau lawv siv tau rau kev siv nyob rau hauv qis- qhov kub thiab txias ib puag ncig los yog nyob rau hauv atmospheric tej yam kev mob.
