Our company was founded in 2000, which initially committed to providing high-quality steel hull of ships use CCS DH40 plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export hull of ships use CCS DH40 plate steel to the international market, opening up the international steel market.
SM520B/C Super heavy steel plate for welded structure, it is also low carbon high strength structural steel with good cold forming property. SM570 Low alloy and high strength steel plate, hull of ships use CCS DH40 plate heavy and wide plate for machinery parts, boom, crane, chassis, buildings bridges and mobile equipment.
hull of ships use CCS DH40 plate, Q215A steel belongs to carbon structural steel. Q215A steel does not contain specially added alloy elements. hull of ships use CCS DH40 plate, Q215A steel is mainly used in construction and engineering structures. Chemical composition of Q215A steel: C: ≤ 0.15, Si: ≤ 0.30, Mn: ≤ 1.20, P ≤: 0.045, S ≤: 0.050. Q215A steel has low carbon and manganese content. Q215A steel strength is slightly higher than Q195 steel strength. hull of ships use CCS DH40 plate, Q215A steel has good plasticity, good toughness, weldability and process performance. Q215A steel is mainly used in plant building, bridge components, tower, derrick and vehicle and ship manufacturing components.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the hull of ships use CCS DH40 plate steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of hull of ships use CCS DH40 plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. hull of ships use CCS DH40 plate, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
