Q355B simbi ndiro

Q355B simbi ndiro ndiro yakaderera-alloy yakakwirira-simba simbi ndiro. Q355B simbi ndiro ine yakanakisa mechaniki basa, yakaderera tembiricha basa, uye yakanakisa plastiki uye weldability. Q355B simbi inoshandiswa kugadzira yepakati uye yakaderera kumanikidza mudziyo, tangi remafuta, mota, crane, muchina wemigodhi, chiteshi chemagetsi, zambuko, nezvimwe.

Kemikari kuumbwa kweQ355B simbi ndiro:
C≤0.24, Si≤0.55, Mn≤1.6, P≤0.035, S≤0.035, Ni≤0.3; Cr≤0.3, N≤0.0012

Mechanical zvimiro zveQ355B simbi ndiro:
Goho simba≥355, tensile simba: 470-630, Akv≥34.

Q355B simbi ndiro inoshandiswa zvakanyanya muinjiniya, muchina wemigodhi, mabhiriji, mota, ngarava, kuvaka, midziyo yekumanikidza, midziyo yakakosha, nezvimwe.
