Q345imhando yesimbi yakaderera alloy inoshandiswa zvakanyanya mumabhiriji, mota, zvikepe, zvivakwa, midziyo yekumanikidza, midziyo yakakosha, nezvimwewo, apo "Q" inoreva kusimba kwegoho, uye 345 zvinoreva kuti simba regoho resimbi iyi 345MPa.
Kuedzwa kweq345 simbi kunonyanya kusanganisira zvinhu zviviri: kutanga, kana chikamu chemukati chesimbi chinosvika pachiyero chenyika; chechipiri, kana goho simba, tensile bvunzo, etc. yesimbi kusangana mipimo kuburikidza nenyanzvi masangano. Iyo ine akasiyana alloy zvemukati kubva q235, inova yakajairwa kabhoni simbi uye q345 yakaderera alloy simbi.
Kurongeka kwezvinhu zveQ345
Q345 inogona kukamurwa kuita Q345A, Q345B, Q345C, Q345D uye Q345E zvichienderana negiredhi. Izvo zvavanomiririra zvakanyanya kuti tembiricha yekukanganisa kwakasiyana. Q345A level, hapana kukanganisa; Q345B nhanho, 20 dhigirii yakajairika tembiricha maitiro; Q345C nhanho, 0 dhigirii kukanganisa; Q345D nhanho, -20 dhigirii kukanganisa; Q345E nhanho, -40 dhigirii kukanganisa. Pamhando dzakasiyana dzetembiricha, kukosha kwemaitiro kwakasiyanawo.
zvakasiyana.
Kushandiswa kweQ345 zvinhu
Q345 ine yakanaka yakazara ma mechanical zvivakwa, inogamuchirika yakaderera tembiricha kuita, yakanaka plasticity uye weldability. Inoshandiswa senge yepakati uye yakaderera midziyo yekumanikidza, matangi emafuta, mota, cranes, muchina wemigodhi, zviteshi zvemagetsi, mabhiriji uye zvimwe zvimiro, mekiniki zvikamu, zvivakwa zvekuvaka, uye zvakajairwa zvimiro zvinotakura mitoro ine simba. Metal structural parts, inoshandiswa mukupisa-yakakungurutswa kana kuti yakajairika, inogona kushandiswa kune akasiyana zvimiro munzvimbo dzinotonhora dziri pasi -40 ° C.
