GB Qib AH 550 GB 712 Mechanical zog
Taw qhia txog cov khoom siv kho tshuab GB Qib AH 550 GB 712:
Yield point(σs) Thaum qhov kev ntxhov siab ntawm GB Qib AH 550 GB 712 lossis cov qauv kuaj pom tau dhau qhov kev txwv elastic nyob rau hauv qhov nro, txawm tias qhov kev ntxhov siab tsis nce, GB Qib AH 550 GB 712 lossis cov qauv yuav txuas ntxiv mus rau qhov pom tseeb ntawm cov yas deformation. Qhov tshwm sim no yog hu ua yielding, thiab qhov tsawg kawg nkaus kev ntxhov siab tus nqi thaum yielding tshwm sim yog hu ua yield point.
Tensile zog (σb): Qhov siab tshaj plaws ntawm GB Qib AH 550 GB 712 thaum lub sij hawm nro txij thaum pib mus rau lub sijhawm tawg. Nws qhia txog lub peev xwm ntawm GB Qib AH 550 GB 712 los tiv thaiv pob txha.
Elongation (δ): Qhov feem pua ntawm cov yas elongation ntev mus rau qhov qub qauv ntev yog hu ua elongation.
Yield-strength ratio(σs/σb): Qhov piv ntawm qhov taw tes tawm los (yield zog) rau lub zog tensile ntawm GB Qib AH 550 GB 712 yog hu ua nws lub zog yield zog piv. Qhov ntau dua qhov yield-strength ratio, qhov siab dua qhov kev ntseeg siab ntawm cov khoom siv.
Hardness: Hardness yog lub peev xwm ntawm GB Qib AH 550 GB 712 los tiv thaiv cov khoom nyuaj nias rau hauv nws qhov chaw. Qhov siab dua qhov hardness, qhov zoo dua qhov hnav tsis kam.

GB Qib AH 550 GB 712 Lub cev muaj zog
Lub cev muaj zog ntawm GB Qib AH 550 GB 712 suav nrog lub zog siab, tsis muaj qhov hnyav, ua haujlwm ntev, ductility thiab tsis kam tiv thaiv corrosion. Hlau, raws li peb txhua tus paub, muaj lub zog zoo txawm tias nws yog qhov hnyav. Qhov tseeb, qhov piv ntawm lub zog rau qhov hnyav rau steel yog qhov qis tshaj li lwm yam khoom siv hauv tsev muaj rau peb.
