Sharaxaada SPCC ee darajooyinka birta duuban ee qabow

1 qeexida magaca
SPCCwuxuu asal ahaan ahaa halbeegga Japan (JIS) "isticmaalka guud eexaashi bir kaarboon duuban qabowiyo strip" birta magaca, hadda wadamo badan ama shirkado si toos ah loo isticmaalo si ay u muujiyaan wax soo saarka iyaga u gaar ah ee birta la mid ah. Fiiro gaar ah: la mid ah darajooyin yihiin SPCD (qabow-rogid kaarboon steel xaashida steel iyo strip for stamping), SPCE ( xaashi steel carbon qabow-rogid iyo strip ee sawir qoto dheer), SPCCK\SPCCCE, iwm siday u kala horreeyaan, marar kala duwan.

2 Qaybaha
Birta Jabbaan (JIS taxane) ee darajada birta qaab dhismeedka caadiga ah waxay ka kooban tahay saddex qaybood oo ka mid ah qaybta hore ee maaddada, sida: S (Steel) in birta, F (Ferrum) in birta; qaybta labaad ee qaababka, noocyada iyo isticmaalka kala duwan, sida P (Plate) in saxanka, T (Tube) in tube, K (Kogu) in qalab; qaybta saddexaad ee sifooyinka lambarka, guud ahaan xoogga ugu yar ee xoogga. Guud ahaan xoogga xajinta ugu yar. Sida: SS400 - S ee ugu horeysay ayaa sheegay in birta (Steel), S labaad wuxuu yiri "qaab-dhismeedka" (Structure), 400 ee xadka hoose ee xoogga korantada ee 400MPa, guud ahaan xoogga korantada ee 400MPa ee birta guud ee dhismaha oo leh awood jilicsan oo 400MPa ah.

Dheeraad ah: SPCC - xaashida birta kaarboon-ka duuban ee qabow iyo xariijimaha si guud loo isticmaalo, oo u dhiganta heerka Shiinaha Q195-215A. Xarafka saddexaad ee C waa qabow qabow oo loo soo gaabiyo. Waxa loo baahan yahay in la hubiyo in tijaabada xajinta, dhamaadka darajada lagu daray T ee SPCCT.
