Q345imhando yesimbi isina alloy yakawanda inoshandiswa zvakanyanya mumabhiriji, mota, ngarava, zvivakwa, midziyo yekumanikidza, michina yakakosha, nezvimwewo, apo "Q" inoreva simba rekupa, uye 345 inoreva kuti simba rekupa resimbi iyi i345MPa.
Kuedzwa kwesimbi yeq345 kunosanganisira zvinhu zviviri: chekutanga, kana zviri mukati mesimbi zvichisvika padanho renyika; chechipiri, kana simba rekugadzira, bvunzo yekudhonza, nezvimwewo zvesimbi zvichisangana nezvinodiwa kuburikidza nemasangano ehunyanzvi. Ine huwandu hwesimbi hwakasiyana neq235, inova simbi yakajairwa yekabhoni uye q345 simbi isina alloy yakawanda.
Kupatsanurwa kwezvinhu zveQ345
Q345 inogona kukamurwa kuita Q345A, Q345B, Q345C, Q345D uye Q345E zvichienderana negiredhi. Zvavanomiririra ndezvekuti tembiricha yekurova yakasiyana. Level yeQ345A, hapana kurova; Level yeQ345B, 20 degrees normal temperature impact; Level yeQ345C, 0 degrees impact; Level yeQ345D, -20 degrees impact; Level yeQ345E, -40 degrees impact. Patembiricha dzakasiyana dzekurova, kukosha kwekurova kwakasiyanawo.
zvakasiyana.
Kushandiswa kwezvinhu zveQ345
Q345 ine hunhu hwakanaka hwemakanika, kushanda zvakanaka kwekupisa kwakaderera, purasitiki yakanaka uye kugona kusundira. Inoshandiswa semidziyo yemagetsi ine simba repakati nepasi, matangi emafuta, mota, makireni, michina yekuchera migodhi, nzvimbo dzemagetsi, mabhiriji nezvimwe zvivako, zvikamu zvemakanika, zvivakwa, uye zvivakwa zvakajairika zvinotakura mitoro inochinja-chinja. Zvikamu zvesimbi, zvinoshandiswa mumamiriro ezvinhu anotonhora kana akajairwa, zvinogona kushandiswa kune zvivakwa zvakasiyana munzvimbo dzinotonhora dziri pasi pe -40°C.
