VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.

Different form Q295NH railway steel, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

Non-destructive flaw detection of steel plates is a test method for inspecting the Q295NH railway steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used Q295NH railway steel 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.
