Advantages and Features

  • High strength: RINA Grade A690 steel plate has a minimum yield strength of 690 MPa, making it suitable for demanding marine applications.
  • Excellent toughness: This steel plate exhibits excellent toughness, ensuring its ability to withstand harsh operating conditions.
  • Good weldability: RINA Grade A690 steel plate can be easily welded using common welding methods, allowing for efficient fabrication.
  • Corrosion resistance: The composition of this steel plate includes elements such as chromium and nickel, which enhance its resistance to corrosion in marine environments.
  • Low temperature impact resistance: The Charpy V-Notch impact test demonstrates the steel plate’s ability to withstand low temperatures, making it suitable for Arctic and sub-Arctic applications.

Application Fields and Uses

RINA Grade A690 steel plate is widely used in the construction of offshore structures, including oil rigs, platforms, and floating production storage and offloading (FPSO) vessels. Its high strength and excellent toughness make it suitable for withstanding the harsh conditions of the marine environment. Additionally, its good weldability allows for efficient fabrication, reducing construction time and costs.

Furthermore, the low temperature impact resistance of RINA Grade A690 steel plate makes it suitable for Arctic and sub-Arctic applications, where extreme cold temperatures are encountered. This steel plate is also used in the construction of icebreakers and other vessels operating in icy waters.

Q&A

Q: Can RINA Grade A690 steel plate be used for onshore structures?

A: While RINA Grade A690 steel plate is primarily designed for offshore structures, it can also be used for certain onshore applications that require high strength and excellent toughness. However, it is important to consider the specific requirements and regulations of the intended application.

Q: What are the certification standards for RINA Grade A690 steel plate?

A: RINA Grade A690 steel plate is certified by the Registro Italiano Navale (RINA), an Italian classification society that sets standards for the design, construction, and maintenance of ships and offshore structures. The certification ensures that the steel plate meets the necessary quality and safety requirements.

Summary

RINA Grade A690 steel plate is a high-strength shipbuilding steel plate that offers excellent toughness, weldability, and corrosion resistance. Its chemical composition includes elements that enhance its properties, while its mechanical properties make it suitable for demanding marine applications.
