Q345C imhando yesimbi yakaderera-alloy yakakwirira-simba rekuvaka simbi: (inoenderana neakare mamakisi pamberi pe88 makore: 16Mn,
12MnV, 14MnNb, 16MnRe, 18Nb mamakisi mashanu akabatanidzwa) Q itsamba yekutanga yeChinese pinyin yeChinese
hunhu "goho", zvichiratidza kusimba kwegoho 345 ndiko kukosha chaiko kwesimba regoho: 345MPa Iyo C pa
kumashure ndiyo yemhando yegiredhi chiratidzo chesimbi yedanho resimba iri, rinowanzo kupatsanurwa kuita A, B, C, D, E uye
mamwe mazinga (akakwira mwero, akakwira mwero) Cherechedza: Iwo magiredhi mashanu A, B, C, D, E haaenderane.
kusvika kumagiredhi mashanu esimbi apfuura, asi magiredhi emhando yepamusoro. Musiyano mukuru ndewekuti zvinodiwa zvekukanganisa
simba rakasiyana: Q345-A: Simba rekuita haridiwe Q345-B: Zvinodiwa zvesimba rekukanganisa mumba.
tembiricha Q345-C: inoda 0 ℃ kukanganisa simba Q345-D: inoda simba rekuita re -20 ℃ Q345-E: inoda
-40 ℃ kukanganisa simba Zvinogona kuoneka kuti anotevera simbi mamakisi anogona kushandiswa pane yakaderera tembiricha
Isu takavaka hukama hurefu uye hwakagadzikana hwekubatana nevatengi mudzimba, seShanghai, Jiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan uye zvichingodaro.
Kumhiri kwemakungwa, mutengi wedu mukuru kubva kuSouth Asia, Africa, South America seSingapore, Vietnam, Brazil, Ghana,
New Zealand, Spain, Mauritius, Dubai nezvimwe.
