P275N Umuyoboro w'icyuma

EN10028 P275N isahani yicyuma / urupapuro, munsi ya EN, turashobora kureba icyuma cya P275N icyuma / urupapuro rwibyuma hamwe nicyuma cya Pressure.EN10028 P275N icyuma cyicyuma / urupapuro ni icyuma hamwe nicyuma cya Pressure, nibisanzwe isahani y'icyuma n'impapuro zikoreshwa cyane cyane mu kubaka imiyoboro y'amashanyarazi hamwe na bombo hamwe n'imiyoboro y'amazi ashyushye.

Mubisanzwe EN10028_3, isahani yicyuma P275N igomba kuba muburyo busanzwe bwo gutanga mugihe itunganijwe.Icyiciro cyicyuma P275NH na P275N gikoreshwa cyane mubyombo byumuvuduko hamwe nicyuma gitandukanya nibindi byuma byububiko bwa karubone_manganese bitewe nubwinshi bwabyo bwokugabanuka kubushyuhe bwose mugihe ukoresheje.
