ASTM A285 Qib C Steel yog tus qauv rau qis / nruab nrab tensile lub zog carbon steel siab nkoj daim hlau. Qib C, qhov siab tshaj - qib zog hauv tus qauv no, yog tsim rau fusion-welded siab hlab ntsha. Nws yog feem ntau muab rau hauv qhov kub - dov (HR), uas yuav tsum tau ua raws li cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam, nrog rau kev txhawb nqa kev tshuaj xyuas thiab vuam specifications.
ASTM A285 steel phaj feem ntau siv hauv:
Kev tsim cov hlab ntsha siab rau kev lag luam roj thiab roj.
Kev tsim kho lub tank thiab boilers.
Cov qauv siv uas xav tau weldability zoo thiab lub zog nruab nrab.
General fabrication qhov twg siab zog tsis yog thawj qhov yuav tsum tau muaj.
