Difference between Q345R boiler vessel plate and ordinary Q345 plate, sa573 gr 70 carbon-manganese-silicon steel:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, sa573 gr 70 carbon-manganese-silicon steel.
