S355J2H cov khoom siv yog cov pa roj carbon tsawg, yooj yim weldable, thiab machineability kuj zoo ib yam li cov hlau me me. s355j2h hollow seem muaj feem xyuam rau hauv petrochemical, roj, thiab roj industries kis tau cov kua thiab gases vim carbon steel yeeb nkab yield zog. S355j2h sib npaug cov kav dej kuj tseem siv hauv kev lag luam marine thiab kev lag luam khoom noj.
