Difference between Q345R boiler vessel plate and ordinary Q345 plate, RINA EH40 hull structural ship plate: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, RINA EH40 hull structural ship plate.
S355J2 steel plate RINA EH40 hull structural ship plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the RINA EH40 hull structural ship plate single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
