Rectangular Steel Tubing Supplier-GNEE
- Plasticity:
Plasticity yog lub peev xwm ntawm cov khoom siv hlau los tsim cov yas deformation (deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
- Hardness:
Hardness yog lub pointer los ntsuas qhov degree ntawm softness thiab hardness ntawm cov ntaub ntawv hlau. Tam sim no nyob rau hauv ntau lawm los txiav txim siab hardness txoj kev uas feem ntau siv yog indentation hardness txoj kev, nws yog ib tug tej yam geometry ntawm lub indenter nyob rau hauv ib tug tej yam load pressed rau saum npoo ntawm cov khoom hlau raug kuaj, raws li qhov degree ntawm raug nias rau hauv kev txiav txim. nws hardness nqi.
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 ua ntej yog taw qhia rau cov khoom siv hluav taws xob ntawm cov hlau nyob rau hauv cov khoom zoo li qub. Qhov tseeb, ntau lub tshuab qhov chaw ua haujlwm nyob rau hauv lub voj voog, nyob rau hauv cov xwm txheej ntawm cov khoom yuav ua rau qaug zog.
- Impact toughness:
Nrog rau kev ceev ceev ntawm lub tshuab qhov chaw ntawm lub load yog hu ua cuam tshuam load, hlau nyob rau hauv kev cuam tshuam load nyob rau hauv qhov kev txiav txim ntawm lub peev xwm los tiv thaiv kev puas tsuaj yog hu ua cuam tshuam toughness.
- Lub zog:
Lub zog yog cov khoom siv hlau nyob rau hauv cov khoom zoo li qub los tiv thaiv kev puas tsuaj (ntau cov yas deformation lossis tawg) kev ua haujlwm. Vim qhov kev txiav txim ntawm lub load nyob rau hauv daim ntawv ntawm tensile, compression, dabtsi yog khoov, shear, thiab lwm yam., yog li ntawd lub zog kuj muab faib ua tensile zog, compressive zog, flexural zog, shear zog, thiab lwm yam.. nruab nrab ntawm ntau yam muaj zog, kev siv lub zog tensile raws li qhov yooj yim lub zog ntawm tus taw tes.
