Bridge steel plates are steel plates specially used to build railway or highway bridges. It is required to have high strength, toughness and bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel SA572 Gr 42 carbon steel material for tie-welding bridges should also have good welding performance and low notch sensitivity。

Difference between Q345R boiler vessel plate and ordinary Q345 plate, SA572 Gr 42 carbon steel material: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, SA572 Gr 42 carbon steel material.
