a242 type 1 weathering bridge steel beam, 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.
Non-destructive flaw detection of steel plates is a test method for inspecting the a242 type 1 weathering bridge steel beam surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used a242 type 1 weathering bridge steel beam steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship. They have a big demand of ship building steel plates with thickness 6mm and thickness 8mm LR AH36 shipping steel a242 type 1 weathering bridge steel beam plates to Senegal Navy, and our strong advantage in offering these ship building steel plates make us begin to build a steady cooperation relationship with Senegal clients. BBN has always supplied high quality ship plates with stable supply. Soon he placed 15 containers of LR AH36 shipping steel plates to BBN.
