Qhov sib txawv ntawm P275NH thiab P355NH steel phaj

Dec 02, 2025 Tso lus

Qhov sib txawv tseem ceeb yog tias P275NH steel muaj qhov siab tshaj qhov ua tau zoo ntawm 275 N / mm², thaum P355NH steel muaj qhov muaj zog tsawg dua ntawm 355 N / mm². Ob leeg yog cov zoo li qub- cov nplej hlau raws li EN 10028-3 tus qauv rau cov hlab ntsha siab, tab sis P355NH muaj zog dua.
