Q: Lub thickness ntawm Q355 steel phaj yog dab tsi?
A: Cov thickness ntau yog 3 hli -200mm. Cov lus qhia tshwj xeeb yog 3mm-100mm, thiab cov phaj tuab ntxiv ntawm 100mm-200mm tuaj yeem kho raws li cov neeg siv khoom xav tau. Lub thickness kam rau ua raws li GB / T 709-2019 tus qauv.
Q: Dab tsi yog qhov dav thiab qhov ntev ntawm Q355 steel phaj?
A: Feem ntau dav: 1000mm, 1220mm, 1500mm, 1800mm, 2000mm, 2200mm, 2500mm; Feem ntau ntev: 2000mm, 2500mm, 3000mm, 6000mm, 12000mm.3} ntev tuaj yeem hloov kho
Q: Q355 steel phaj puas tuaj yeem txias- tsim?
A: Yog. Q355 steel phaj muaj qhov txias txias zoo thiab tuaj yeem ua tiav rau hauv ntau yam duab (xws li cov ces kaum, raws, kav, nkhaus daim hlau) los ntawm kev khoov txias, stamping thiab lwm yam txheej txheem. Rau cov phaj tuab los yog kev sib sau ua ke, preheating yog pom zoo kom tsis txhob tawg.
Q: Dab tsi yog qhov weldability ntawm Q355 steel phaj?
A: Q355 steel plate has excellent weldability and can be welded by various methods (arc welding, gas welding, resistance welding, submerged arc welding, etc.). No preheating is required for thin plates during welding; for plates with thickness >25mm los yog qis-kub vuam, preheating rau 80-150℃yog pom zoo kom tiv thaiv kom txhob txias tawg.
Q: Q355 steel phaj puas tuaj yeem ua kom sov- kho?
A: Yog. Cov txheej txheem kev kho cua sov feem ntau suav nrog normalizing, annealing thiab tempering. Kev kho kom zoo tuaj yeem ua kom zoo dua cov nplej, txhim kho lub zog thiab toughness ntawm steel phaj; kev kho annealing tuaj yeem txo qhov hardness thiab txhim kho lub machinability; tempering kev kho mob tuaj yeem tshem tawm cov kev ntxhov siab welding thiab txhim kho cov qauv kev ruaj ntseg.
