The RINA DH460/D460 marine steel plates are high-strength materials specifically designed for the construction of ships and marine structures. These steel grades are approved by the Italian Register of Shipping and Classification Society (RINA) and are widely recognized for their excellent mechanical properties and durability in harsh marine environments.

Chemical Composition

The chemical composition of RINA DH460/D460 steel plates plays a pivotal role in determining their overall performance. These steel grades typically contain carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, molybdenum, and copper in carefully controlled proportions. The precise balance of these elements ensures high strength, good weldability, and corrosion resistance.

Mechanical Properties

The mechanical properties of RINA DH460/D460 steel plates are outstanding. These steel grades exhibit high yield strength and tensile strength, making them suitable for applications that require exceptional structural integrity. Additionally, they possess good toughness and ductility, allowing them to withstand impact loads and deformation without failing.

Heat Treatment Status

The heat treatment status of RINA DH460/D460 steel plates is crucial for achieving their desired mechanical properties. These steel grades are typically subjected to normalizing or quenching and tempering processes to enhance their strength and toughness. These heat treatment techniques refine the steel's microstructure, improving its resistance to fatigue and corrosion.

Size Range

RINA DH460/D460 steel plates are available in a range of thicknesses, widths, and lengths to meet the specific requirements of marine construction projects. Whether it's for hull plates, deck plates, or other structural components, these steel grades can be customized to fit the desired dimensions.

Impact Testing

Impact testing is an essential part of the quality control process for RINA DH460/D460 steel plates. This testing involves subjecting the steel to low-temperature impact loads to assess its resistance to brittle fracture. The steel grades must meet strict impact toughness requirements to ensure their safety and reliability in extreme conditions.
