Q245R Pressure Vessel Steel Plate
Q245R vessel plate is a steel plate for boilers and pressure vessels. The implementation standard of Q245R boiler plate is the special technical conditions of GB/T247.
Q245R pressure vessel steel itself not only has very high strength, but also has certain toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, hydrogen resistance and other high-quality properties.
Q245R boiler steel plate is often used in boiler and container manufacturing industries, such as pressure vessel manufacturing, nuclear capacitor manufacturing, reactors, heat exchangers, large chemical container equipment, etc.
