Q345 S235 C Tshooj Hlau

Q345 Hlau yog ib hom hlau uas tsis tshua muaj hlau, uas yog siv rau hauv kev tsim cov choj, cov tsev, thiab lwm yam khoom siv. Nws muaj lub zog tawm los ntawm 345 MPa thiab tensile lub zog ntawm 470-660 MPa.S235 qib steel yog ib qho yooj yim weldable tsawg carbon manganese hlau nrog zoo cuam tshuam tsis kam (xws li nyob rau hauv sub-zero kub).Cov khoom no feem ntau muab nkag rau hauv tsis kho lossis tsis zoo li qub thiab muaj nyob rau hauv ntau qhov kev hloov pauv (ntaus los ntawm cov ntawv ntxiv thiab / lossis tus lej), uas muaj kev hloov kho me ntsis ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.
