Do you know the xar400 plate equivalent gradesheat treatment?

Q235 steel is ordinary carbon structural steel, also called Q235 ms plate. Q235 steel plates are popular among a large number of buildings and engineering structures. Q235 steel can be used to make steel bars or to build workshop frames, high-voltage transmission towers, bridges, vehicles, boilers, vessels, ships, etc. Q235 steel is also widely used as xar400 plate equivalent grades mechanical parts with low performance requirements. Sometimes Q235C steel and Q235D steel can also be used as special steel.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, xar400 plate equivalent grades: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, xar400 plate equivalent grades.

In actual processing applications, the processing xar400 plate equivalent grades thickness of flame cutting ranges from 6 to 200 mm, and the xar400 plate equivalent grades cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting xar400 plate equivalent grades with a certain thickness above 10mm.
