Q: Qhov txawv ntawm Q355 thiab S355 steel phaj yog dab tsi?
A: Qhov sib txawv tseem ceeb yog cov txheej txheem txheej txheem. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab yog qhov zoo ib yam, tab sis cov kev soj ntsuam xyuas thiab cov qauv kam rau ua txawv me ntsis. Peb Q355 daim hlau tuaj yeem ua tau raws li cov neeg siv khoom nyob sab Europe los ntawm kev sim thib peb (xws li SGS, BV).
Q: Dab tsi yog lwm qib ntawm Q355 phaj hauv Suav qub qauv?
A: Q355 yog qib tshiab hauv GB / T 1591-2018, hloov cov qib qub Q345 hauv GB / T 1591-2008. Lub zog tawm los ntawm Q355 yog me ntsis siab dua Q345, thiab kev ua haujlwm ruaj khov dua.
Q: Dab tsi ua cov txheej txheem Q355 tuaj yeem raug rau?
A: Q355 phaj tuaj yeem ua tiav los ntawm kev txiav (nplaim taws, txiav ntshav, txiav laser), khoov, dov, drilling, vuam, thiab polishing, uas yog tsim rau ntau yam kev ua haujlwm.
Q: Dab tsi yog qhov siab tshaj plaws ntawm Q355 phaj uas tuaj yeem raug nplaim taws?
A: Peb Q355 daim hlau tuaj yeem raug nplaim taws txiav los ntawm 3mm txog 300mm. Rau cov phaj tuab dua 100mm, peb pom zoo kom siv preheating thiab txiav qeeb kom ntseeg tau tias qhov kev txiav zoo.
Q: Q355 puas tuaj yeem khoov rau hauv lub vojvoog me me?
A: Yog, qhov tsawg kawg nkaus dabtsi yog khoov vojvoog yog hais txog lub thickness: rau daim hlau nrog thickness Tsawg dua los yog sib npaug rau 10 hli, qhov tsawg kawg nkaus khoov vojvoog yog 1.5 npaug ntawm thickness; rau cov phaj tuab, nws yog 2-3 zaug lub thickness. Kev khoov txias yog pom zoo kom tsis txhob txo lub zog.
