Our company was founded in 2000, which initially committed to providing high-quality steel ZQS700L cold forming 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 ZQS700L cold forming steel to the international market, opening up the international steel market.

There are many types of ZQS700L cold forming etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.

Pipeline steel is a kind of steel specially used for transporting natural gas and petroleum with special requirements. Why do oil and gas pipelines use pipeline steel as the transportation pipeline? Because pipeline steel has the following characteristics. First, the pipeline steel is strong, and it is not easy to break. If it breaks during transportation, the consequences are unimaginable. Second, the ZQS700L cold forming, pipeline steel is durable. Pipeline steel is buried deep underground for a long time and has good corrosion resistance. Third, the pipeline steel is resistant to high temperature and will not deform under high temperature.

After extrusion, the ZQS700L cold forming tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. ZQS700L cold forming, S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
