Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.
Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.
The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as EN 10025 S355ML steel price steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of EN 10025 S355ML steel price steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
We have a professional production team and high-quality production equipment, and we also have a great EN 10025 S355ML steel price advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the EN 10025 S355ML steel price production of high-quality steel plates, steel pipes and other products that meet customer requirements.
We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
