Mild Steel Hlau Qauv Hlau H Beam S275J {1}}
Qhov "s" hauv S275J {1}} tus qauv steel sawv ruaj khov rau MPa, thiab "J}" sawv rau qhov kev ntsuas zoo rau kev cuam tshuam ntawm {}}}} degree. S275J 0 h cis tau siv dav siv hauv kev tsim kho thiab kev tsim khoom vim lawv lub zog, kev nruj thiab weldability.
Qhov Zoo ntawm S275J 0} me me steel nqaj
Nruab Nrab Lub zog rau qhov hnyav piv txwv: Haum rau nruab nrab txheej txheem txheej txheem txheej txheem.
Qhov khoom siv tsis tshua muaj cua kub: Haum rau ib puag ncig uas muaj qhov kub uas muaj tsawg li 0 degree.
Zoo tshaj Weldability: tsawg cov ntsiab lus cov pa roj carbon tsawg txo qhov kev pheej hmoo ntawm kev tawg thaum vuam.
Txhim khu kev qha ua tau: Cov khoom siv neeg siv cov khoom siv xws li pab tau kev ua tau zoo heev.
Cia thiab tuav txoj kev ntawm S275J {1}}} cov roj carbon h nqaj
Khaws rau hauv qhov chaw qhuav, muaj qhov cua kom tsis txhob ya raws.
Tsis txhob sib cuag ncaj qha rau hauv av; Siv pallets lossis racks.
Kov nrog kev saib xyuas kom tsis txhob muaj kev cuam tshuam lossis kev puas tsuaj thaum lub sijhawm thauj mus los.
S275J {0 beads yog dav siv hauv kev tsim kho thiab kev tsim kho kom zoo thiab muaj zog ntawm qhov kub thiab txias. Cov kev siv cov ntawv thov uas suav nrog: lub tsev ua cov thav ntawv thiab cov txheej txheem kev txhawb nqa; Txuas hniav thiab cov neeg sib tw hauv huab cua txias; Cov chaw muaj chaw thiab cov chaw khaws khoom; hnyav machinery gases thiab platforms; Kev tsim kho dav dav thiab kho ua haujlwm.
