LR AH36 Structural Steel Material Hot Rolled Ship Building Steel Plate
A demand for heavy thick plates with a good combination of high strength, toughness, and weldability has been widely growing in recent years for large container ship building. Because of this, e tra high-strength termomechanically processed steels TMCP have been developed to be more user friendly than the traditional steels.
Excellent handling properties are based on thermomechanical treatment that reduces the need for e cessive use of alloying elements to strengthen the steel. TMCP plates are thermomechanically controlled rolled, and with greater plate thicknesses, also accelerated cooled after rolling.
Overview:
Higher-strength steel grades certified for use in shipbuilding capacities.
Available in four ordinary-strength grades: A, B, D and E.
Available in 12 higher-strength grades, but Gnee only readily stocks grades AH36, DH36, EH36 and FH36. Other higher-strength grades, may be special ordered.
Used in the building of structural parts of ships, barges and marine equipment.
MATERIAL PROPERTIES
The following material properties required by LR and will be confirmed on the Mill Test Report. Elongation is dependent on plate thickness, but is listed in a range below.
