I-Q345C luhlobo lwentsimbi ephantsi-i-alloy ephezulu yolwakhiwo lwentsimbi: (ehambelana namabakala amadala ngaphambi kweminyaka eyi-88: 16Mn,
12MnV, 14MnNb, 16MnRe, 18Nb amabanga amahlanu adityanisiweyo) Q yileta yokuqala yepinyin yaseTshayina yamaTshayina
umlinganiswa "isivuno", ebonisa amandla esivuno 345 lixabiso elithile lamandla esivuno: 345MPa I C at
umva luphawu lwebakala lomgangatho wentsimbi yeli nqanaba lamandla, ngokubanzi lahlulwe ku-A, B, C, D, E kunye
Amanye amanqanaba (inqanaba eliphezulu, liphezulu inqanaba) Qaphela: Amabanga amahlanu A, B, C, D, E akangqinelani.
ukuya kumabakala entsimbi amahlanu adlulileyo, kodwa umgangatho. Umahluko ophambili kukuba iimfuno zempembelelo
amandla ahlukile: Q345-A: Amandla empembelelo ayifunwa Q345-B: Iimfuno zempembelelo yamandla kwigumbi
iqondo lobushushu Q345-C: lifuna 0℃ impembelelo yamandla Q345-D: ifuna amandla empembelelo ye -20℃ Q345-E: ifuna
-40 ℃ impembelelo yamandla Inokubonwa ukuba amabakala entsimbi alandelayo angasetyenziswa kumaqondo obushushu aphantsi
Siye sakha ubudlelwane bexesha elide kunye nozinzile kunye nabathengi basekhaya, njengeShanghai, iJiangsu,
Zhejiang, Anhui, Shandong, Jiangxi, Qinghai, Liaoning, Hainan njalo njalo.
Ngaphesheya kolwandle, umxhasi wethu ophambili osuka eMzantsi Asia, eAfrika, eMzantsi Melika njengeSingapore, Vietnam, Brazil, Ghana,
INew Zealand, iSpain, iMauritius, iDubai njl.
