Diferans ant plak asye P275NH ak P355NH

Dec 02, 2025 Kite yon mesaj

Diferans prensipal la se ke P275NH asye gen yon pi wo fòs sede minimòm nan 275 N / mm², pandan y ap asye P355NH gen yon pi wo fòs sede minimòm nan 355 N / mm². Tou de se nòmalize amann amann -anba estanda EN 10028-3 pou veso presyon, men P355NH pi fò.
