Square Tube Performance

Cov yas
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.

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.

Kev 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.

Impact 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.

Kev siv ntawm Square Tube

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.
