What Is P460QH Steel Plates?
P460QH steel plates are a specific grade of steel defined by the EN 10028-6 standard, primarily used for manufacturing welded pressure vessels and boilers. They are known for their high strength, weldability, and suitability for low-temperature applications. The "QH" designation indicates a -20°C temperature and 27J impact energy requirement.
