ASTM A210 seamless steel yeeb nkabyog ib hom seamless steel yeeb nkab rau nruab nrab thiab qis siab boilers. Nws yog siv los tsim ntau yam tsawg thiab nruab nrab siab boilers, superheated chav kav, boiling dej kav, dej phab ntsa kav thiab superheated chav kav, cov pa luam yeeb loj thiab me me kav dej rau locomotive boilers. Cov kav dej thiab arch cib kav, thiab lwm yam.
ASTM A210 seamless steel kav tau muab faib ua ob pawg: A1 thiab C. Qeb A1 steel kav muaj qis carbon thiab silicon cov ntsiab lus thiab feem ntau yog siv rau headers thiab cua sov nto kav uas yuav tsum tau muaj zog dua thiab loj dua cua sov; Qeb C steel kav muaj qis manganese cov ntsiab lus, cov ntsiab lus silicon siab, feem ntau yog siv rau hauv cov kav dej cua sov, kev lag luam, superheaters, reheaters, petrochemical kev lag luam kav, thiab lwm yam.
