S275JOH puag ncig carbon steel raj
S275JOH carbon steel yeeb nkabyog ib qho qis-alloy high-strength structural steel uas belongs rau qib hauv European tus qauv EN 10025-2. Nws yog tsuas yog siv los tsim cov khoom hnyav xws li kev tsim vaj tsev, txuas hniav, tsheb, thiab nkoj. Nws cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab tau ua kom zoo dua los muab lub zog siab, toughness thiab vuam kev ua tau zoo.
Cov tshuaj muaj pes tsawg leeg ntawm S275JOH Mild steel yeeb nkab yog raws li nram no 1: Carbon C. Cov ntsiab lus Tsawg dua los yog sib npaug rau 0.20. Silicon Si. Cov ntsiab lus Tsawg dua lossis sib npaug rau 0.55. ManganeseMn. Cov ntsiab lus Tsawg dua lossis sib npaug rau 1.60. Sulfur S. Cov ntsiab lus Tsawg dua lossis sib npaug rau 0.035. Phosphorus P. Cov ntsiab lus Tsawg dua lossis sib npaug rau 0.035.
Cov ntsiab lus ntawm cov khoom siv tshuaj no yog los xyuas kom meej tias S275JOH steel yeeb nkab muaj cov khoom siv zoo heev thiab kev ua haujlwm vuam, thaum ua tau raws li qhov xav tau ntawm ntau yam kev thov.
Qhov tsawg kawg nkaus lub zog ntawm S275JOH carbon seamless steel yeeb nkab yog 275MPa. Tus nqi no yog tus nqi tus qauv, qhia txog qhov kev ntxhov siab tsawg kawg nkaus uas cov khoom pib tawm los deformation thaum raug rau ib qho kev ntxhov siab. Txawm li cas los xij, hauv kev tsim khoom tiag tiag, vim muaj kev cuam tshuam ntawm cov khoom siv zoo, kev siv thev naus laus zis thiab lwm yam, lub zog tawm los tiag tiag yuav siab dua lossis qis dua tus nqi tus qauv no.
