Q420 simbi ndiro

Q420 Steel Sumo
Q420 simbi ichiChinese giredhi resimbi yeLow Alloy High Strength Structural Steel, Goho Simba i420 MPa, maparameter anoedzwa ne 16mm dhayamita simbi simbi kana marata esimbi, uye kusimba kwesimbi i520-680 Mpa, density i7.85 g/ /cm3. Maererano neGB/T 1591-2008, Q420 ine 5 mhando dzemazinga: Q420A, Q420B, Q420C, Q420D neQ420E. Kune Q420 simbi yakaenzana, chimiro chemakemikari uye michina zvivakwa, ndapota ona matafura ari pazasi emukati.
Features uye Mashandisirwo
Q420 simbi ine simba rakawanda, kunyanya mune yakajairwa kana yakajairwa uye yakadzama mamiriro, ine yakakwira yakazara mekiniki zvivakwa, inogona kushandiswa mungarava hombe, mabhiriji, magetsi echiteshi chemagetsi, epakati uye akakwira dhizaini boilers, yakakwira midziyo yekumanikidza, michina yekusimudza, michina yemigodhi uye. zvimwe hombe welded structural parts.
