Qhov sib txawv tseem ceeb ntawm P355ML1 thiab P355ML2 steel yog qhov tsawg kawg nkaus qhov kev xav tau ntawm lub zog, nrog rau P355ML2 yuav tsum muaj kev cuam tshuam ntau dua ntawm qhov kub thiab txias dua P355ML1. Qhov no yog vim P355ML2 tshwj xeeb tsim los rau qis-kev siv kub, xws li cov hlab ntsha siab, thaum P355ML1 yog ib qho dav dav- hom phiaj steel qib uas yuav tsum tau nruj me ntsis rau nws cov khoom cuam tshuam.
