RINA EH690 and RINA E690 are high-strength marine steel plates that are specifically designed to meet the rigorous standards set by the Italian Register of Shipping (RINA) for use in the construction of ships and offshore structures. These grades of steel plates possess exceptional mechanical properties, chemical composition, and heat treatment states, making them ideal for a wide range of marine applications.

The chemical composition of RINA EH690 and RINA E690 steel plates is carefully controlled to ensure optimal performance in marine environments. The primary alloying elements, such as carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, nickel, copper, and vanadium, are carefully balanced to achieve the desired strength, toughness, and corrosion resistance.

In terms of mechanical properties, these steel plates exhibit high yield strength and tensile strength, making them suitable for structures that require exceptional load-bearing capacity. Additionally, they possess good ductility and toughness, allowing them to withstand the dynamic loads and impact forces encountered in marine operations.

The heat treatment state of RINA EH690 and RINA E690 steel plates is critical to achieving the desired mechanical properties. These steel plates are typically supplied in a quenched and tempered condition, which involves heating the steel to a high temperature and then rapidly cooling it to induce the desired microstructural changes. This process results in a fine-grained microstructure that enhances the strength and toughness of the steel.

Regarding size range, RINA EH690 and RINA E690 steel plates are available in a variety of thicknesses, widths, and lengths to meet the specific requirements of marine construction projects. The ability to customize the dimensions of these steel plates allows for efficient material utilization and reduced waste during the construction process.

Impact testing is an essential part of the quality control process for RINA EH690 and RINA E690 steel plates. This testing involves subjecting the steel to low-temperature impact loads to assess its resistance to brittle fracture. The results of these tests ensure that the steel plates can withstand the extreme cold temperatures encountered in some marine environments without compromising their structural integrity.

The primary application scenarios for RINA EH690 and RINA E690 steel plates include the construction of hulls, decks, and other structural components of ships and offshore platforms. These steel plates are also used in the fabrication of bridges, piers, and other marine infrastructure that requires high strength and corrosion resistance.
