S355NL saxan bir ah

S355N steel waa darajada birta qaab dhismeedka. S macneheedu waa birta qaab dhismeedka, 355 macnaheedu waa daqida soosaarka xoogga dhumucdiisuna waxay ka yar tahay 16mm ee Mpa, NL macnaheedu waa xaalada dhalmada.

Is barbar dhig S275N/s275NL, birta S355NL waxay leedahay waxsoosaar badan iyo xoog xajin. Heerka siman ee S355NL waa S355ML.

Birta birta ah waxay bixin kartaa dhumucda ugu badan ilaa 350mm iyada oo la isticmaalayo ingot Ballaca ugu badan  3800mm, waxaanu sidoo kale samayn karnaa tijaabada UT, tijaabada saamaynta, falanqaynta kiimikaad, tijaabada farsamada, iyo daawaynta la ekayd iyada oo la raacayo shuruudaha macmiilkayaga.

Ku saabsan S355NL macluumaadka faahfaahsan ee birta, fadlan tixraac taariikhda farsamada ee soo socota.

Kiimikada ayaa ah halabuurka ugu badan ee falanqaynta alaabta:
