EN P 420 M EN 10028-5 Lub cev muaj zog
Cov khoom siv lub cev ntawm EN P 420 M EN 10028-5 suav nrog lub zog siab, 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.
