Q345luhlobo lwentsimbi ephantsi ye-alloy esetyenziswa ngokubanzi kwiibhulorho, izithuthi, iinqanawa, izakhiwo, iinqanawa zoxinzelelo, izixhobo ezikhethekileyo, njl., apho "Q" ithetha amandla okuvelisa, kwaye i-345 ithetha ukuba amandla okuvelisa le ntsimbi yi-345MPa.
Uvavanyo lwentsimbi ye-q345 ikakhulu lubandakanya imiba emibini: okokuqala, ingaba umxholo wensimbi ufikelela kumgangatho wesizwe; okwesibini, nokuba amandla isivuno, uvavanyo tensile, etc. yentsimbi ukuhlangabezana nemigangatho ngamaziko professional. Inomxholo ohlukeneyo we-alloy ukusuka kwi-q235, eyintsimbi ye-carbon eqhelekileyo kunye ne-q345 i-alloy iron ephantsi.
Ukuhlelwa kwezinto ze-Q345
I-Q345 inokwahlulwa ibe yi-Q345A, i-Q345B, i-Q345C, i-Q345D kunye ne-Q345E ngokwebakala. Into abayimeleyo ikakhulu kukuba ukushisa kwempembelelo kuyahluka. Inqanaba le-Q345A, akukho mpembelelo; Inqanaba le-Q345B, i-20 degree impembelelo yeqondo lokushisa eliqhelekileyo; Inqanaba le-Q345C, impembelelo ye-0 degree; Inqanaba le-Q345D, impembelelo ye-20 degree; Inqanaba le-Q345E, -40 impembelelo ye-degree. Kumaqondo obushushu eempembelelo ezahlukeneyo, amaxabiso eempembelelo nawo ahlukile.
ezahlukeneyo.
Ukusetyenziswa kwezinto ze-Q345
I-Q345 ineempawu ezilungileyo ezibanzi zoomatshini, ukusebenza okwamkelekileyo kobushushu obuphantsi, iplastiki elungileyo kunye nokushisela. Isetyenziswe njengemikhumbi yoxinzelelo oluphakathi kunye noluphantsi, iitanki ze-oyile, izithuthi, iikhreyini, oomatshini bemigodi, izikhululo zamandla, iibhulorho kunye nezinye izakhiwo, iinxalenye zoomatshini, izakhiwo zokwakha, kunye nezakhiwo eziqhelekileyo ezithwala imithwalo eguquguqukayo. Izakhiwo zesinyithi, ezisetyenziswa kwiimeko ezishushu okanye eziqhelekileyo, zingasetyenziselwa izakhiwo ezahlukeneyo kwiindawo ezibandayo ezingaphantsi kwe-40 ° C.
