High strength Q345E alloy steel plates stock in China

　　Q345E high strength alloy steel plate is mainly used in the production of bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines and steel structures.

　　Additional services: cutting, grinding, milling and heat treatment

　　Q345E steel plate performance requirements

　　(1) High strength: Generally, its yield strength is above 300MPa.

　　(2) High toughness: Elongation is required to be 15% to 20%, and the impact toughness at room temperature is greater than 600kJ / m to 800kJ / m. For Q345E welding parts, higher fracture toughness is also required.

　　(3) Good welding performance and cold forming performance.

　　(4) Low cold brittle transition temperature.

　　(5) Good corrosion resistance.
