P355NH birta

EN 10028 P355NH/NL1/NL2
Markabka cadaadiska birta oo leh alxan wanaagsan iyo iska caabin sare oo dildilaaca, P355NH waxaa isticmaala dunidu wax-soo-saareyaasha si ay u soo saaraan taangiyada weelka cadaadiska ee kaydinta gaaska la cadaadiyo.

Noocyada kale ee darajada waxaa ka mid ah...
NL1 - waxay ku habboon tahay isticmaalka heerkulka hooseeya
NL2 - waxay ku habboon tahay isticmaalka gaar ahaan heerkulka hooseeya
P355NH waa darajada birta caadiga ah oo leh ugu yaraan wax soo saarkiisu yahay 275-460 N/mm² iyo taargooyin hore ayaa laga heli karaa bakhaarkeena.
