C-CARBON STEEL ibyuma bya karubone, A, b, na C byerekana imbaraga zubwoko bwibyuma kuva hasi kugeza hejuru.
WCA, WCB, WCC byerekana ibyuma bya karubone, bifite imikorere myiza yo gusudira nimbaraga za mashini.ABC yerekana urwego rwimbaraga, rusanzwe rukoreshwa WCB.Ibikoresho by'imiyoboro ihuye na WCB bigomba kuba A106B, naho ibikoresho bihimbano ni A105.Bikwiranye na valve munsi yubushyuhe busanzwe nigitutu.
WC6 ni ugutera ibyuma bivanze.Ifite ubushyuhe buhebuje bwo kurwanya ubushyuhe hamwe na antioxydeant kandi ikwiranye na valve munsi yubushyuhe bwinshi nubushyuhe bukabije.
Ibikoresho bihuye bijyanye na A355 P11, naho igice cyo guhimba ni A182 F11;
Hiyongereyeho, hari WC9, ibyuma -ubushyuhe bwo hejuru cyane, bihwanye na A355 P22, kandi guhimba bigomba guhura na A182 F22.
WC welding casting ifite imbaraga nubukomezi.Birakwiriye mubikorwa bisanzwe byinganda.
LCB / LCC (ASTM A352) Icyuma gike-ubushyuhe bwa karubone ifite ubukana buke no kurwanya ruswa.Irakwiriye kubushyuhe buke -ubushyuhe bukabije bwa progaramu, nka gaze ya LPG (LNG).
