LR AH69/LR A69 are high-strength shipbuilding steel plates specifically designed for use in the marine industry. These plates exhibit exceptional strength, toughness, and weldability, making them ideal for constructing hull structures of ships and offshore platforms.

Chemical Composition

The chemical composition of LR AH69/LR A69 steel plates is carefully controlled to ensure optimal mechanical properties. Typical elements include carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), nitrogen (N), and copper (Cu), among others. The precise balance of these elements ensures the desired strength and ductility of the steel.

Mechanical Properties

The mechanical properties of LR AH69/LR A69 steel plates are exceptional. They exhibit high yield strength, tensile strength, and elongation, making them suitable for demanding applications. Additionally, the steel demonstrates good impact toughness, which is crucial for withstanding the rigors of the marine environment.

Heat Treatment State

LR AH69/LR A69 steel plates are typically supplied in a normalized or controlled rolling condition. This heat treatment ensures uniform microstructure and mechanical properties throughout the plate, optimizing its performance in service.

Size Range

LR AH69/LR A69 steel plates are available in a wide range of sizes to cater to different shipbuilding requirements. The thickness of these plates typically ranges from 6 mm to 150 mm, with widths and lengths varying according to specific orders.

Impact Testing

Impact testing is conducted on LR AH69/LR A69 steel plates to assess their ability to withstand sudden impacts. This testing is particularly important for marine applications where the steel may be exposed to collision or accidental damage. The steel demonstrates impressive impact resistance, meeting or exceeding industry standards.

Main Applications

LR AH69/LR A69 steel plates are primarily used in the construction of ships, including cargo ships, tankers, container ships, and cruise ships. They are also suitable for offshore platforms, bridges, and other marine structures that require high-strength and toughness.
