Marine Grade Hot Rolled Ship Building Steel Plate LR AH36
Ship building steel plate has a strict control on chemical
composition of steel as per requirements of domestic and
international shipbuilding standards CCS, GL, BV, ABS, DNV, LR, NK,
KR, RINA or GB712. This use of controlled-rolling and controlled-
cooling process as per carbon equivalent in hot-rolling leads to
stable chemical composition and excellent mechanical properties of
the ship steel plate.
The surface of ship building steel plates is flat, the edge is
even, and the diagonal bias is small. The precision of the ship
building steel size is high, and the thickness difference of the
same plate is small. The ship building steel, with about 0.1%
copper, has a good corrosion resistance. The ship building steel
also has a good welding performance with a low carbon equivalent.
