A514GrQ ship offshore platform steel plate

A514GrQ steel plate is a quenched and tempered high-strength weldable steel plate for ship offshore platform. The main purpose is to use in places requiring high tensile strength and high yield strength, such as engineering car lifting gears, racks for marine channels, etc.
A514GrQ steel plates thickness: 3mm to 150mm
Shapes: round bar, plates, sheets
Steel plate delivery status: delivered in quenched and tempered (quenched + tempered) state

With the continuous development of my country's marine economy, especially under the strategic background of vigorously developing the ocean, the construction of marine platforms has ushered in a new period of rapid development. However, because offshore platforms have to withstand the erosion and damage of natural forces such as waves, tsunamis, storms, submarine earthquakes, and low temperatures, they have extremely high requirements on various technical indicators of steel. The technical standards for steel use in key parts such as racks and pile legs are even higher. For harsh. A514GrQ large-thickness rack steel plate is the key material for manufacturing jack-up offshore drilling platform legs. It has the characteristics of high strength, high toughness, large thickness, strong corrosion resistance, high technical content and difficult production. At the same time, it is required to have -40℃ impact toughness, yield strength not less than 690Mpa, and lamellar tear resistance. What is more difficult is that its impact toughness must be detected at 1/2 of the thickness of the steel plate, and the impact energy value is greatly improved.
