A514Gr.F steel for making racks of offshore platform

A514 Gr.F steel is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is characterized by high strength and good welding performance. A514Gr.F welded steel plate has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Mainly used in places requiring high tensile strength and high yield, such as drilling rigs, lifting gears, oil derricks, coal mine hydraulic supports, electric shovel, electric wheel dump trucks, loaders, bulldozers, and various cranes used in mines and various engineering constructions , Engineering vehicle lifting gears, large excavators, marine drilling platforms, mining equipment, etc.

The racks for offshore platforms generally use A514Gr.F. Its hardness is between 235-290, its yield is greater than 630MPa, and its tensile strength is greater than 700MPa. A514Gr.F quenched and tempered steel plate is mainly used for making racks of jack-up offshore drilling platforms.
