The marine industry relies heavily on high-quality steel plates that can withstand the rigors of oceanic environments. Among the trusted grades for such applications, RINA DH36 and RINA D36 shipbuilding steel plates stand out for their exceptional properties. These grades are specifically designed to meet the strict standards of the Italian Register of Shipping (RINA) for use in various shipbuilding and offshore structures.

Chemical Composition

The chemical composition of RINA DH36 and RINA D36 steel plates is carefully controlled to ensure optimal performance. These grades typically contain carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, copper, molybdenum, and vanadium in precise proportions. The balance of these elements provides the steel with excellent strength, toughness, and corrosion resistance.

Mechanical Properties

The mechanical properties of RINA DH36 and RINA D36 steel plates are noteworthy. These grades exhibit high yield and tensile strengths, coupled with good elongation and impact toughness. These properties enable the steel plates to perform reliably under extreme loading conditions, such as wave impact and dynamic loads encountered during ship operations.

Heat Treatment State

The heat treatment state of RINA DH36 and RINA D36 steel plates is crucial to their performance. These grades are typically supplied in a normalized or quenched and tempered condition, depending on the specific requirements of the application. Normalized steel has improved toughness and weldability, while quenched and tempered steel offers higher strength and hardness.

Dimensional Range

RINA DH36 and RINA D36 steel plates are available in a wide range of thicknesses, widths, and lengths to suit various shipbuilding and offshore projects. The plates can be customized to meet specific project requirements, ensuring efficient material utilization and cost-effectiveness.

Impact Testing

Impact testing is a crucial aspect of ensuring the reliability of RINA DH36 and RINA D36 steel plates. These grades undergo rigorous impact testing at low temperatures to assess their toughness and resistance to cracking. This testing ensures that the steel plates can withstand extreme environmental conditions without compromising their structural integrity.

Main Applications

RINA DH36 and RINA D36 steel plates are widely used in various shipbuilding and offshore applications. They are commonly employed in the construction of hulls, decks, and other structural components of ships and offshore platforms. Their excellent strength and corrosion resistance make them suitable for use in both freshwater and marine environments.
