Q345E Low Alloy Steel Plate
The density of Q245R boiler steel plate is 7.85g/cm3, which is mainly used to manufacture various boilers and important accessories. Since the Q245R pressure vessel steel plate works at medium temperature (below 350°C) and high temperature, in addition to high pressure, the boiler also bears impact, fatigue load and water and gas corrosion.
GNEE steel is a professional exporter and steel distributor of Q245R boiler steel plate in China. We have more than 50,000 tons of Q245R pressure vessel plate in stock every month. We provide rust removal, cutting, punching, bending, welding and other services. For Q245R vessel steel plate prices, please feel free to contact us by email or phone.
