Q345B Square Tube
Q345B square tube, 16Mn square tube, Q345B square tube, square tube, square tube, square raj, seamless square raj, stainless hlau square raj, square rectangular raj, q345b square tube, loj txoj kab uas hla tuab-walled square tube, Q345C square tube, stainless hlau square raj Rectangular steel kav, seamless square rectangular steel kav thiab lwm yam square yeeb nkab khoom.
Q345B square raj yog tsim raws li lub teb chaws tus qauv GBT 6728-2002 txias-tsim hollow seem steel rau qhov loj, zoo, qhov hnyav thiab tso cai sib txawv ntawm cov qauv. Nws yog ua los ntawm Q345B sawb hlau tom qab ua thiab dov. Q345B square tube yog ua los ntawm Q345B cov khoom siv (tsawg alloy), uas txawv heev ntawm cov square raj zoo tib yam hauv cov khoom siv raw (Q195, Q215, Q235). Feem ntau, Q345B strip steel (tsawg alloy) yog unpacked. , flattened, crimped, welded los ua ib puag ncig lub raj, thiab ces dov mus rau hauv ib lub raj square los ntawm lub round raj thiab ces txiav mus rau hauv qhov ntev yuav tsum tau. Qhov ntev li ib txwm yog 6 meters, thiab qhov loj ntawm 12 meters tuaj yeem ua tiav raws li cov neeg siv khoom xav tau. Feem ntau, qhov me me yog 50 daim ib pob, thiab qhov loj loj yog 4 daim txhua thiab qhov hnyav yog tswj ntawm li 3 tons. Q345B square tubes feem ntau yog 80MM * 80MM-500MM * 500MM hauv cov lus qhia loj hauv Tshuag, thiab cov tuab yog 3MM-16MM.
Q345B square raj seamless thiab welded
Q345B seamless square raj yog tsim los ntawm extruding Q345B seamless round raj.
Q345B square tube plasticity
Plasticity yog hais txog lub peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
Q345B square tube hardness
Hardness yog ib qho kev ntsuas ntawm hardness ntawm cov ntaub ntawv hlau. Txoj kev siv feem ntau rau kev ntsuas hardness hauv kev tsim khoom yog txoj kev indentation hardness, uas siv ib qho indenter ntawm ib qho duab geometric los nias rau saum npoo ntawm cov khoom hlau yuav tsum tau kuaj nyob rau hauv ib tug tej yam load, thiab hardness tus nqi yog txiav txim raws li. degree ntawm indentation.
Cov kev siv feem ntau suav nrog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV).
Q345B square tube yog lub hollow square seem lub teeb nyias-walled steel raj, tseem hu ua steel tub yees dabtsi yog khoov seem. Nws yog ib feem hlau nrog ib tug square cross-section duab thiab loj ua los ntawm Q345B kub dov los yog txias dov sawb los yog coil raws li lub hauv paus khoom, uas yog tsim los ntawm txias dabtsi yog khoov thiab ces welded los ntawm high-frequency vuam. Ntxiv nrog rau qhov thickening ntawm phab ntsa thickness ntawm kub-dov-tuab phab ntsa square raj, lub ces kaum loj thiab ntug flatness tau mus txog los yog txawm tshaj cov theem ntawm cov kuj welded txias-tsim square raj.
Q345B square tube siv
Q345B square kav feem ntau yog siv rau hauv kev tsim kho, tshuab tsim, steel tsim cov haujlwm, kev tsim nkoj, kev txhawb nqa lub hnub ci, steel qauv engineering, fais fab engineering, fais fab nroj tsuag, kev ua liaj ua teb thiab tshuaj machinery, iav kab hlau rhuav phab ntsa, tsheb chassis, tshav dav hlau, thiab lwm yam.
Q345B square yeeb nkab ceg hnyav xam mis: 4 sab ntxiv * thickness * 0.00785 * ntev
Q345B duab plaub cov yeeb nkab txhawb nqa qhov hnyav suav cov mis: (sab ntev + sab ntev) * 2 * 0.00785 * phab ntsa tuab * ntev
