AH32 grade marine board

What is AH32 grade marine board?

AH32 high-strength hull structural steel is used to make the hulls of various ocean-going ships and inland water ships, and steel plates for offshore ships refer to hot-rolled steel plates for manufacturing hull structures produced in accordance with the requirements of the classification society's construction regulations.
There are two types of steel for hull structure: general strength steel and high strength steel. The quality of general strength steel is divided into four grades: A, B, D, and E; high strength steel is divided into two strength grades and three quality grades: AH32 , DH32, EH32, AH36, DH36, EH36.

Market application of AH32 ship plate:

Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion of seawater, electrochemical corrosion, and corrosion of marine organisms and microorganisms. The hull is subjected to large wind and wave impacts and alternating loads. Steel requirements are strict, and marine steel plates are produced in accordance with the construction specifications of classification societies. They are used to manufacture hot-rolled steel plates for hull structures. AH36 and DH36 ship plates not only have high strength, but also have good toughness and corrosion resistance. Performance and welding, processing performance, the product is widely used in various types of engineering machinery, such as drilling rigs, electric shovels, electric wheel reverse bucket trucks, mining vehicles, excavators, loaders, bulldozers, various Mechanical equipment such as cranes, coal mine hydraulic supports and other structural parts.
