Puas yog koj tab tom nrhiav rau tus neeg xa khoom zoo tshaj plaws ntawmS355j aik kav hlau kav hlau?
S355j2h yog qhov qis-} manganese steel {}} Txawm nyob rau hauv sub {}}} tshaj} xoom} xoom} xoom} xoom}. Raws li qib kawm nyob rau hauv EN 10210 tus qauv, "cov qauv J2" qhia tau tias muaj cov khoom siv hollow, thaum lub "h" raws li cov kav dej hollow thiab cov qauv txheej txheem. Cov "s" sawv rau cov qauv hlau, ua rau 10219 S3219 S355J2H Seamless Pipe zoo tagnrho rau kev tsim kho thiab kev siv khoom lag luam.
Txhim kho nrog manganese, no cov roj carbon stick muaj kev txhim kho hardness thiab kav ntev. Nrog cov phab ntsa thicker piv rau cov kav dej txheem, S355J2H Hollow seem muab lub zog tshwj xeeb thiab kev ntseeg tau. Xaiv EN 10219 S355J2H kub ua tiav cov ntu Hollow (CHS) rau kev ua kom ruaj khov thiab ntev}} kav dej ib puag ncig.
Qhov zoo tshaj plaws rau B2B cov neeg yuav khoom nrhiav siab- Cov khoom siv tau zoo, thiab txhim khu kev ua haujlwm zoo nkauj - kev ua haujlwm kub.
