I-Q345C iwuhlobo lwensimbi yesakhiwo esinengxubevange ephansi: (ehambisana namamaki amadala ngaphambi kweminyaka engama-88: 16Mn,
12MnV, 14MnNb, 16MnRe, 18Nb amabanga amahlanu ahlanganisiwe) Q uhlamvu lokuqala lwe-pinyin yesiShayina yamaShayina
uhlamvu “isivuno”, okubonisa amandla esivuno esingu-345 inani elithile lamandla esivuno: 345MPa I-C at
ingemuva iwuphawu lwezinga lensimbi lwaleli zinga lamandla, ngokuvamile elihlukaniswe ngo-A, B, C, D, E kanye
amanye amazinga (izinga eliphezulu, izinga eliphezulu) Qaphela: Amabanga amahlanu A, B, C, D, E awahambisani
emabangeni ensimbi amahlanu adlule, kodwa amamaki ekhwalithi. Umehluko omkhulu ukuthi izidingo nomthelela
amandla ahlukile: Q345-A: Amandla okuthinta awadingeki Q345-B: Izidingo zamandla omthelela ekamelweni
izinga lokushisa Q345-C: lidinga 0℃ amandla omthelela Q345-D: lidinga amandla omthelela angu -20℃ Q345-E: idinga
-40℃ amandla omthelela Kungabonakala ukuthi amamaki ensimbi alandelayo angasetshenziswa emazingeni okushisa aphansi
Sakhe ubudlelwano bokubambisana besikhathi eside nezinzile namakhasimende asekhaya, njengeShanghai, Jiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan njalonjalo.
Ngaphesheya kwezilwandle, iklayenti lethu elikhulu elivela eNingizimu Asia, e-Afrika, eNingizimu Melika njengeSingapore, Vietnam, Brazil, Ghana,
New Zealand, Spain, Mauritius, Dubai njll.
