  Details:
 LR DH36 and LR D36 are high-strength shipbuilding steel grades used in the construction of maritime vessels and offshore structures. These grades offer excellent strength and toughness, making them suitable for use in demanding environments.

Chemical Composition

The chemical composition of LR DH36 and LR D36 steel plates is carefully controlled to ensure optimal mechanical properties. These grades typically contain carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (Si), and trace elements such as nickel (Ni), chromium (Cr), copper (Cu), and molybdenum (Mo). The exact composition varies depending on the specific grade and manufacturer's standards.

Mechanical Properties

LR DH36 and LR D36 steel plates exhibit high yield strength and tensile strength, making them suitable for use in structural applications. The yield strength of LR DH36 is typically 355 MPa, while the tensile strength ranges from 490 to 620 MPa. LR D36, on the other hand, has a yield strength of 345 MPa and a tensile strength ranging from 450 to 590 MPa. Both grades also exhibit good ductility and impact resistance.

Heat Treatment

LR DH36 and LR D36 steel plates are typically heat-treated to achieve the desired mechanical properties. The heat treatment process involves heating the steel to a high temperature, holding it for a specified duration, and then cooling it controlled rates. This process helps to refine the grain structure, improve the mechanical properties, and ensure consistent quality throughout the plate.

Dimensional Range

LR DH36 and LR D36 steel plates are available in a wide range of dimensions to meet the specific requirements of various applications. The thickness of these plates typically ranges from 6 mm to 150 mm, while the width and length can vary depending on the manufacturer and customer requirements.

Impact Testing

To ensure the safety and reliability of LR DH36 and LR D36 steel plates in low-temperature environments, they are subjected to impact testing. This testing involves striking a notched specimen with a pendulum at a specified temperature to assess the plate's ability to absorb energy without fracturing. The plates are designed to meet specific impact energy requirements, depending on the grade and the intended application.

Main Application Scenarios

LR DH36 and LR D36 steel plates are widely used in the construction of ships, barges, offshore platforms, and other marine structures. They are particularly suitable for applications that require high strength and toughness in harsh environments, such as those exposed to extreme temperatures, corrosive seawater, and wave impact.
