Why is water seeping out of the slit when cutting S690QL elastic modulus

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product S690QL elastic modulus structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel S690QL elastic modulus supplier in the world.

45Mn carbon structural steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness. It is generally used in the quenched and tempered state, and S690QL elastic modulus can also be used in Used in quenched and tempered or normalized state.

S690QL elastic modulus, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.

After extrusion, the S690QL elastic modulus 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.
