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
