LR AH32 DH32 EH32 FH32 Steel Plate Supplier and Manufacturer

Lloyd’s Register Grades AH32, DH32 and EH32 FH32 are higher-strength structural steels with a specified minimum yield strength of 46 ksi and specified minimum Charpy V-notch impact toughness properties.Marine steel plate refers to structural steel used in ship building. It is considered a marine grade and must be able to resist corrosive effects that are common in a water environment. To achieve this, special alloying elements are added to these grades in order to defend agaist corrosion.While most carbon steel is not suited for marine environments, there are several marine grade carbon steels that have been approved by the different societies for shipbuilding applications.

Applications

Typical applications include ships and other structural applications.
