P460NH Pressure Vessel Steel Plate
P460NH boiler steel plate is a special steel plate for European standard pressure vessels. It has the characteristics of high strength, good toughness, excellent corrosion resistance and good weldability. It is widely used in many fields such as petroleum, chemical industry, power station, boiler, etc.
P460NH steel boiler plate not only has high strength, but also good toughness, good low temperature toughness, and can maintain good performance at lower temperatures.
