A500 Carbon Steel Square Tubing, raws li lub npe implies, nws yog ib tug square zoo ntawm lub raj, ntau yam khoom muaj peev xwm tsim ib square raj lub cev, nws nruab nrab nyob rau hauv, dab tsi siv, qhov twg siv, feem ntau ntawm cov square yeeb nkab rau hlau. yeeb nkab rau feem ntau, feem ntau yog rau cov qauv square yeeb nkab, kho kom zoo nkauj square yeeb nkab, lub tsev square yeeb nkab thiab lwm yam.
Square yeeb nkab yog ib lub npe rau cov yeeb nkab square, uas yog, cov yeeb nkab steel nrog ntev sib npaug ntawm ob sab.Nws yog ua los ntawm sawb hlau tom qab ua tiav thiab dov.Feem ntau, lub sawb yog unpacked, leveled, crimped thiab welded rau hauv ib puag ncig raj, uas yog dov mus rau hauv ib lub raj square thiab ces txiav mus rau hauv qhov ntev yuav tsum tau.Feem ntau 50 sticks rau ib pob.
Classification Thiab Performance
Seamless A500 Carbon Steel Square Tubing muab faib ua seamless thiab weld, seamless square yeeb nkab yog ua los ntawm seamless round raj extrusion.Square steel yeeb nkab, tuab phab ntsa square steel yeeb nkab, loj txoj kab uas hla square steel yeeb nkab, seamless square steel yeeb nkab, tsis tshua muaj hlau square steel yeeb nkab, 135 * 135 * 10 square steel yeeb, ntauwd crane square steel yeeb nkab, Q345B tsawg alloy square steel yeeb nkab, 20 # seamless square steel yeeb nkab
1. Performance index tsom xam ntawm square steel raj - plasticity
Plasticity yog hais txog lub peev xwm ntawm cov khoom siv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
2. Performance index tsom xam ntawm square steel raj - hardness
Hardness yog qhov ntsuas ntawm qhov nyuaj lossis muag cov khoom siv hlau.Tam sim no, feem ntau siv txoj kev los txiav txim siab hardness hauv kev tsim khoom yog txoj kev indenter hardness, uas yog siv cov duab geometric ntawm lub taub hau indenter nyob rau hauv ib qho kev thauj khoom mus rau saum npoo ntawm cov khoom siv hlau kuaj, raws li qib ntawm cov khoom siv. indenter los txiav txim nws tus nqi hardness.
Cov kev siv feem ntau yog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV) thiab lwm txoj kev.
3. Performance index tsom xam ntawm square steel raj - qaug zog
Lub zog, plasticity, thiab hardness tau tham saum toj no yog cov cim ntawm cov khoom siv hluav taws xob ntawm cov hlau hauv qhov chaw thau khoom zoo li qub.Qhov tseeb, ntau lub tshuab ua haujlwm tau ua haujlwm nyob rau hauv lub voj voog, thiab qaug zog tuaj yeem tshwm sim nyob rau hauv cov xwm txheej no.
4. Performance index tsom xam ntawm square steel yeeb nkab - cuam tshuam toughness
Lub load ua rau ntawm qhov chaw ntawm kev kub ceev yog hu ua cuam tshuam load, thiab lub peev xwm ntawm hlau los tiv thaiv kev puas tsuaj nyob rau hauv kev cuam tshuam load yog hu ua cuam tshuam toughness.
5. Performance index tsom xam ntawm square steel raj - lub zog square steel raj, tuab phab ntsa square steel raj, loj txoj kab uas hla square steel raj, seamless square steel raj, tsis tshua muaj hlau square steel raj, 135 * 135 * 10 square steel raj, ntauwd crane square steel raj, Q345B qis alloy square steel raj, 20 # seamless square steel raj
Lub zog yog lub peev xwm ntawm cov khoom siv hlau los tiv thaiv tsis ua haujlwm (ntau cov yas deformation lossis tawg) nyob rau hauv qhov chaw thau khoom zoo li qub.Vim yog hom kev thauj khoom nyob rau hauv daim ntawv ntawm stretching, compression, dabtsi yog khoov, shearing, yog li lub zog kuj muab faib ua tensile zog, compressive zog, dabtsi yog khoov zog, shear zog thiab thiaj li nyob.Feem ntau muaj qee qhov kev sib txuas ntawm ntau lub zog, thiab lub zog tensile feem ntau yog siv los ua tus taw qhia lub zog tshaj plaws.
Xaus puab:oblique kawg, tiaj tus kawg, ploj lossis ntxiv cov yas npog los tiv thaiv qhov xaus raws li cov neeg siv khoom xav tau Oiled, galvanized, pleev xim rau dub
Technology:kub dov, txias dov
