LR AH36 Structural Steel Plate
What is the Shipbuilding Steel Plate?
The Shipbuilding Plate Ah36 comes under the specification of ASTM A131/A131M grade. These plates have a good impact strength and work well in different marine ecosystems. This lr shipbuilding steel plate is a high-strength grade that is usually hot rolled and possesses good tensile strength. These plates are divided into twelve grades. The shipbuilding steel plate lr grade a is the most common grade that has moderate corrosion resistance in the systems. These grades are subjected to an impact force of 20 degrees C. A grade a shipbuilding steel plate can be custom designed in a wide range of shapes and sizes as per product requirements. If you have any queries or questions or want to get a quote on these plates, contact us for more information.
Shipbuilding Steel Classification
The standard strength steel of China Classification Society is divided into four quality grades: A, B, C, and D, namely, CCSA, CCSB, CCSC, and CCSD. The high strength structural steel regulated by the China Classification Society is three strength grades and four quality grades.
Common grades are A, B, D, E, AH32/36/40, DH32/36/40, and EH32/36/40 which ranged from different strength. The plates usually used to manufacture ship hulls, bulkheads, upper decks and hatch covers for tankers, bulk carriers, container ships and LNG carriers.
For the high strength shipbuilding plates like AH36, DH36, EH36 steel plate, they have been widely used in high stress areas of ships, comparing with general strength steel, they are offering the same strength with the smaller thickness.
Shipbuiding Standards from Different Countries
Shipbuilding steel plates are produced according to the classification society,different countries refers to offshore and marine steels in different classification society. Mainly as following:
ABS (American Bureau of Shipping)
BV (Bureau Veritas)
CCS (China Classification Society)
DNV (Det Norske Veritas)
GL (Germanischer Lloyd)
HR (Hellenic Register of Shipping)
KR (Korean Register of Shipping)
LR (Lloyd's Register of Shipping)
NK (Nippon Kaiji Kyokai)
RINA (Registro Italiano Navale)
RS (India Register of Shipping)
What Is Thickness Of Shipbuilding Plate?
The thickness of Shipbuilding Plates ranges between 5 mm to 150 mm. It can be customized according to the specific requirements of the client.
