P355NH maitai

Ko te taaputanga ASTM A537 e hipoki ana i nga pereti waro waro kua werahia mo nga tono oko pehanga.
Whakataki hua
EN 10028 P355NH/NL1/NL2
He karaehe rino oko pehanga me te pai o te weldability me te atete nui ki te pakaru pakarukaru, ka whakamahia te P355NH e nga kaihanga o te ao mo te hanga i nga taika waka pehanga mo te rokiroki o nga hau pehanga.

Ko etahi atu momo tohu ko...
NL1 - he pai mo te whakamahi i nga waahi iti
NL2 - he pai mo te whakamahi i roto i nga waahi iti rawa
Ko te P355NH he karaehe rino kua whakaritea me te iti rawa o te kaha hua o te 275-460 N/mm² me nga pereti e waatea ana i mua i to maatau whare putunga.
