Ko te Q345C he momo rino hanganga iti-kokorua teitei: (e rite ana ki nga tohu tawhito i mua i te 88 tau: 16Mn,
12MnV, 14MnNb, 16MnRe, 18Nb e rima nga tohu kua hanumi) Ko Q te reta tuatahi o te pinyin Hainamana o te Hainamana.
pūāhua "tuku", e tohu ana i te kaha o te tuku 345 ko te uara motuhake o te kaha tuku: 345MPa Ko te C i
ko te tuara te tohu tohu kounga o te maitai o tenei taumata kaha, ka wehewehea ki A, B, C, D, E me
etahi atu taumata (ka teitei ake te taumata, ka teitei ake te taumata) Tuhipoka: Ko nga reanga e rima A, B, C, D, E karekau e rite
ki nga tohu rino e rima o mua, engari ko nga tohu kounga. Ko te rereketanga nui ko nga whakaritenga mo te paanga
He rereke te kaha: Q345-A: Kare e hiahiatia te mana paanga Q345-B: Nga whakaritenga mo te kaha paanga i te ruma
pāmahana Q345-C: me 0℃ pūngao pānga Q345-D: me whai pūngao pānga -20℃ Q345-E: me hiahia
-40 ℃ pūngao pānga Ka kitea ka taea te whakamahi i nga tohu maitai e whai ake nei i te iti o te mahana
Kua hanga e matou he hononga mahi mo te wa roa me te pumau me nga kaihoko i roto i nga kaainga, penei i Shanghai, Jiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan me etahi atu.
Mo tawahi, ko ta matou kaihoko matua mai i Ahia ki te Tonga, Awherika, Amerika ki te Tonga penei i Singapore, Vietnam, Brazil, Ghana,
Aotearoa, Spain, Mauritius, Dubai etc.
