Q345C ndi mtundu wa otsika aloyi mkulu-mphamvu structural zitsulo: (lolingana ndi sukulu zakale pamaso zaka 88: 16Mn,
12MnV, 14MnNb, 16MnRe, 18Nb magiredi asanu ophatikizidwa) Q ndi chilembo choyamba cha pinyin yaku China ya Chitchaina
khalidwe "zokolola", kusonyeza mphamvu ya zokolola 345 ndi mtengo weniweni wa zokolola mphamvu: 345MPa The C at
kumbuyo ndi chizindikiro khalidwe kalasi ya chitsulo cha mlingo mphamvu, zambiri ogaŵikana A, B, C, D, E ndi
Magawo ena (okwera, okwera kwambiri) Zindikirani: Magiredi asanu A, B, C, D, E sagwirizana.
mpaka magiredi asanu apitawa achitsulo, koma magiredi abwino. Kusiyana kwakukulu ndikuti zofunikira pakukhudzidwa
mphamvu ndizosiyana: Q345-A: Mphamvu yamphamvu siyofunika
kutentha Q345-C: kumafuna 0 ℃ mphamvu yamphamvu Q345-D: imafuna mphamvu ya -20 ℃ Q345-E:
-40 ℃ mphamvu yamphamvu Zitha kuwoneka kuti magiredi achitsulo otsatirawa angagwiritsidwe ntchito pa kutentha kochepa
Tamanga mgwirizano wautali komanso wolimba ndi makasitomala m'nyumba, monga Shanghai, Jiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan ndi zina zotero.
Kutsidya kwa nyanja, kasitomala wathu wamkulu wochokera ku South Asia, Africa, South America monga Singapore, Vietnam, Brazil, Ghana,
New Zealand, Spain, Mauritius, Dubai etc.
