Birta P275NH

EN 10028 P275NH /NL1/NL2
275NH waa bir qafiif ah oo welded ah oo ku haboon samaynta weelasha cadaadiska ee gaaska la cadaadiyo iyo kiimikooyinka, kuleyliyeyaasha warshadaha, kombaresarada iyo kulaylka. Darajada waxaa loogu talagalay in lagu isticmaalo adeeg heerkul dhexdhexaad ah ama heer sare ah.

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

Gnee steel  waxa ay ku siisaa P275NH kaydka oo adiga ayay kuu keenaysaa. Taarikadayada kaarboonka waxa kale oo lagu tijaabiyaa heerarka ugu adag taas oo ka dhigaysa ku habboonaanta kaydkayaga mid sii weyn oo hubinaysa inaad si dhakhso leh u keento.
