S275 kub- dov steel yog dab tsi?
S275yog ib qho qis- carbon kub- dov cov qauv hlau nrog qhov tsawg kawg nkaus tawm lub zog ntawm 275 MPa. Qhov no txhais tau tias nws yog siab -lub zog, yooj yim rau vuam, thiab yooj yim rau txheej txheem thiab daim ntawv.
Dab tsi yog qee qhov kev xaiv zoo rau S275 steel?
Cov kev xaiv zoo rauS275 hlausuav nrog ASTM A36 lossis A572 Gr. 42 (rau kev siv cov qauv siv dav dav) thiab S355 (rau kev siv zog dua). Rau cov ntawv thov uas yuav tsum tau muaj kev ua haujlwm qis -kub, S275NL lossis ASTM A633 Gr. A yog cov kev xaiv zoo dua li cov qauv kev xaiv.
Puas yog ASTM A36 thiab S235JR sib npaug?
Yog lawm, ASTM A36 thiabS235 JRraug suav hais tias sib npaug hauv ntau daim ntawv thov vim tias lawv muaj cov tshuaj lom neeg zoo sib xws thiab cov khoom siv kho tshuab, tshwj xeeb tshaj yog hais txog lub zog thiab weldability.
Peb hom kub -rolled steel yog dab tsi?
Kub-rolled steelFeem ntau yog muab faib ua peb pawg raws li nws cov ntsiab lus carbon: qis- carbon steel, nruab nrab- carbon steel, thiab siab - carbon steel. Tsis tas li ntawd, nws tseem tuaj yeem raug cais raws li cov khoom tsim thiab cov txheej txheem ua haujlwm ntxiv.
Qhov twg zoo dua, txias- dov steel (CR) lossis kub- dov steel (HR)?
Txias-rolled steel (CR) yog qhov tsim nyog rau cov ntawv thov uas xav tau siab precision, lub zog, thiab nto tiav, thaumkub-rolled steel(HR) yog qhov tsim nyog rau kev siv dav dav -cov phiaj xwm siv nrog cov kev xav tau qis dua rau qhov raug thiab qhov pom, muab tus nqi zoo dua - ua tau zoo.
