CCS-AH36 and CCS-DH36 ship plates are special steel plates for marine platforms and marine engineering, referred to as AH36 and DH36. AH36 and DH36 ship plates are also called high-strength plates, low-alloy high-strength plates, and high-strength welded plates. A and D are Quality level, the quality level is divided into 4 levels, namely A, D, E, F. H represents high-strength building materials, 36 is the maximum compression value, and is produced according to GB/T712-2011 standard.
Mechanical properties of AH36 and DH36 ship plates:

Tensile test: upper yield strength ≥355REh/MPa
Tensile strength 490-630Rm/MPa
Elongation after break ≥21A%
V-type impact test: test temperature 0℃, -20℃
Thickness ≤50mm (vertical and transverse), impact absorption energy not less than 34, 24
Thickness 50mm-70mm (vertical and transverse), impact absorption energy not less than 41, 27
Thickness 70mm-150mm (vertical and transverse), impact absorption energy not less than 50, 34
AH36 and DH36 ship plates also have added performance requirements for steel plate thickness in the Z direction, and Z backward is AH36-Z35 and DH36-Z35.
Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion, electrochemical corrosion, and corrosion from marine organisms and microorganisms in seawater. The hull withstands large wind and wave impacts and alternating loads. The shape of the ship makes the processing method complicated and other factors, so the hull structure is Steel requirements are strict. Marine steel plates are produced according to the requirements of classification society construction specifications. They are hot-rolled steel plates used to manufacture ship hull structures. AH36 and DH36 ship plates not only have high strength, but also have good toughness and corrosion resistance. performance, welding and processing performance, this product is widely used in various types of engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, etc. for mining and various engineering constructions. Cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.
