Mechanical Properties of Structural Steel 420

Cov khoom siv ntawm cov qauv hlau kuj tseem ceeb heev rau nws cov kev faib tawm, thiab tom qab ntawd nws daim ntawv thov. Cov qauv hlau 420 muaj qhov zoo tensile thiab tawm los lub zog thiab lawv tau tabulated hauv qab no

Khoom	Txhais	Tus nqi
Tensile zog	Lub ntsiab lus ntawm qhov kev hloov pauv mus tas li tshwm sim thaum cov khoom rub tawm lossis ncab tom qab raws nws qhov ntev.	480-620 MPa (ntawm nominal thickness ntawm 3 thiab 16mm)
Yield zog	Lub zog tawm los ntawm cov qauv hlau ntsuas qhov tsawg kawg nkaus quab yuam yuav tsum tsim kom muaj qhov deformation mus tas li hauv cov hlau.	60.915 ksi (420 N / mm2) [ntawm nominal thickness 16mm]
