LR AH36 and LR A36 are two grades of high-strength shipbuilding steel plates that are widely used in the construction of ocean-going vessels and offshore structures. These grades are developed to meet the specific requirements of the marine industry, ensuring durability, safety, and reliability under harsh operating conditions.

Chemical Composition

LR AH36 and LR A36 steel plates are composed of carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and other trace elements. The carbon content is carefully controlled to ensure good weldability and toughness. Silicon and manganese are added to enhance strength and workability, while phosphorus and sulfur are kept to low levels to maintain the mechanical properties of the steel.

Mechanical Properties

These steel grades exhibit excellent mechanical properties, including high yield strength, tensile strength, and impact toughness. LR AH36 has a higher yield strength than LR A36, making it suitable for more demanding applications. Both grades have good ductility and toughness, which are crucial for resisting impact loads and absorbing energy in case of collisions or accidents.

Heat Treatment State

LR AH36 and LR A36 steel plates are typically supplied in a normalized or controlled rolling condition. This heat treatment improves the microstructure of the steel, enhancing its mechanical properties and weldability.

Size Range

The size range of LR AH36 and LR A36 steel plates is quite extensive, covering thicknesses from several millimeters to over 100 millimeters. Widths and lengths can also be customized to meet specific project requirements.

Impact Testing

To ensure their suitability for use in cold environments, LR AH36 and LR A36 steel plates undergo impact testing at low temperatures. This testing verifies the ability of the steel to maintain its mechanical properties when exposed to extreme weather conditions.

Main Application Scenarios

LR AH36 and LR A36 steel plates are primarily used in the construction of large ocean-going vessels, such as cargo ships, container ships, and cruise ships. They are also suitable for offshore structures like oil platforms, drilling rigs, and pipelines. These grades offer superior durability and resistance to corrosion, making them ideal for use in saltwater environments.
