LR Grade AH32 Marine Steel Plate Supplier and Manufacturer

LR Grade AH32,LR AH32,LR AH32 steel plate is mainly used to build vessels&docks which are sailing in near-ocean waters.We offer wide heavy shipbuilding plate,up to today,we can supply the maximum thickness for shipbuilding plate Grade AH32 shall be 400mm,and the maximum width shall be till 4200mm.This owned world-class property.For the thickness above 40mm,our engineers suggest customers accept doing Normalized heat treatment for LR Grade AH32 steel plates.

Heat Treatment State

LR AH32/LR A32 steel plates undergo a controlled heat treatment process to optimize their mechanical properties. This treatment involves heating the steel to a specific temperature, holding it for a period of time, and then cooling it slowly to ensure uniform properties throughout the plate.

Size Range

LR AH32/LR A32 steel plates are available in a wide range of sizes to cater to different shipbuilding requirements. These plates are typically available in thicknesses ranging from several millimeters to tens of millimeters, and in widths and lengths tailored to specific projects.

Impact Testing

To ensure the structural integrity of ships and offshore structures, LR AH32/LR A32 steel plates undergo rigorous impact testing. These tests simulate extreme conditions, assessing the ability of the steel to absorb energy and resist fracture under impact loads.

Main Application Scenarios

LR AH32/LR A32 steel plates find widespread application in the construction of ships, offshore platforms, and other marine structures that require high strength and durability. These plates are particularly suitable for use in areas exposed to harsh marine environments, where corrosion resistance and fatigue strength are critical.
