Q345E thick plate Wugang production and steel plate cutting and blanking

1. Introduction to Q345E steel plate:
1. Introduction to
Q345E steel plate Q345E is a low-alloy high-strength structural steel, or low-carbon steel. Q345E has high yield strength, fatigue resistance; High toughness and low brittle transition temperature; ** Cold forming properties and welding properties; It has good corrosion resistance and certain wear resistance.
2. The implementation standard of Q345E steel plate: GB/T1591-2008, the new standard is GB/T1591-2018, and the corresponding grade is Q355NE
3, Q345E steel plate delivery status: steel plate is delivered
in the state of hot rolling, controlled rolling, normalizing, normalizing rolling, normalizing plus tempering, thermomechanical rolling (TMCP) or thermomechanical rolling plus tempering

(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of

GB/T222 6, Q345E application scope:
7, Q345E steel plate thickness direction performance When the steel plate is required to have thickness direction performance
, Then the symbols Z15, Z25 and Z35 representing the performance level in the thickness direction are added after the grades specified above.
8. Q345E steel plate thickness range: Wugang low-alloy steel plate can produce a thickness range of 8~700mm, and the material performance is guaranteed to 400mm; The steel plate can be cut with zero cutting, and special-shaped parts can be cut.
9. Q345E steel plate smelting method: steel is smelted by converter or electric furnace, and can be refined outside the furnace if necessary.
10. Q345E steel plate size, shape, weight and allowable deviation Q345E steel plate size, shape, weight and allowable deviation
shall comply with the provisions of the corresponding standard of GB/T 709.
11. Q345E steel plate application range
Q345E is suitable for power towers, all kinds of lifting cranes, heavy trucks, oil derricks, high-temperature fans, large electric shovels, dump trucks and drilling rigs, and coal mine hydraulic supports
