Non-destructive flaw detection of steel plates is a test method for inspecting the SM520B carbon steel plate sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used SM520B carbon steel plate sheet 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.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate SM520B carbon steel plate sheet for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 SM520B carbon steel plate sheet and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
