High toughness and low brittleness transition temperature: with the increase of the working pressure of the A514 grade P structural steel material gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure A514 grade P structural steel material pipeline safety, toughness and strength must be improved at the same time.
Difference between Q345R boiler vessel plate and ordinary Q345 plate, A514 grade P structural 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, A514 grade P structural steel material.
For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of A514 grade P structural steel material stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the A514 grade P structural steel material stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.
We have a professional production team and high-quality production equipment, and we also have a great A514 grade P structural steel material advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the A514 grade P structural steel material production of high-quality steel plates, steel pipes and other products that meet customer requirements.
