P355NH simbi

EN 10028 P355NH/NL1/NL2
Chidimbu chesimbi giredhi ine yakanaka weldability uye yakakwirira kuramba brittle cracking, P355NH inoshandiswa nevagadziri vepasirese kugadzira matangi emidziyo yekumanikidza kuchengetedza magasi akamanikidzwa.

Dzimwe mhando dzegiredhi dzinosanganisira...
NL1 - yakanakira kushandiswa mukupisa kwakadzika
NL2 - yakanakira kushandiswa kunyanya kudziya kwakadzika
P355NH igiredhi resimbi rakajairwa rine simba rekushomeka re275-460 N/mm² uye ma plates anowanikwa ex-stock kubva mudura redu.
