The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. EN10025-4 S275ML steel, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce EN10025-4 S275ML steel, hot-rolled seamless steel tube by continuous rolling mill.
Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, EN10025-4 S275ML steel, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.
According to EN10025-4 S275ML steel traders in some regions, the downstream purchasing sentiment is maintained, the inventory resources are relatively small, and the EN10025-4 S275ML steel traders are more willing to strike a deal; in addition, the domestic steel mills have issued guidance prices recently, and the long-term upward range is large, which has a boosting effect on the market. In addition, there are EN10025-4 S275ML steel production line maintenance at the end of the month, so the supply side is tight. Overall, the short-term forecast for EN10025-4 S275ML steel will fluctuate mainly upwards tomorrow.
