Cov yam ntxwv ntawm S275J 0 h nqaj steel qauv

Zoo weldability thiab machinability: nws tuaj yeem muab tau yooj yim nrog lwm cov neeg sib tw weldable, muaj kev ua tau zoo txias, thiab yog ib qho yooj yim rau cov txheej txheem thiab tsim khoom.

Nruab Nrab Lub Zog: lub zog yog siab dua li ntawm S235 qib steel thiab qis dua li ntawm cov cai tsim, xws li cov qauv qauv, kev txhawb nqa qauv, thiab lwm yam.

Gnee steel tau tsim tsa nyob rau xyoo 2008, peb cov khoom tseem ceeb yog seem steel, lub tsev sib luag, thiab lwm yam. Peb zoo siab los muab koj tus nqi zoo tshaj plaws thiab cov lus qhia. Koj zoo siab tos txais koj mus ntsib peb lub tuam txhab.
