Katalor Passed The Classification Society Certificates Description
The katalor shipbuilding panels are widely used to manufacture general strength and high strength steel for ship hull structures in ocean, coastal and inland river navigation areas; since 1998, katalor and class B ship plates have been approved by the China Classification Society factory for shipbuilding, in order to adapt to the shipbuilding industry. The chemical composition of the ship plate is required. In 1998, Katalor shipbuilding steel A, B, AH32, and AH36 were approved by the China, Britain, and Norway classification societies. In 2001, the AH32 and AH36 high-strength ship plates passed the medium and The British, French, German, American, Norwegian, Italian, Korean, Japanese and other nine classification societies approved the certificate of ship board quality. In 2005, D, DH32 and DH36 ship steel plates passed Chinese, English, French, German and American. The factories of nine classification societies in Norway, Italy, Korea and Japan are recognized.
Ship plate grades: A, B, D, E, A32, A36, D32, D36, E32, E36, and 9 national classification societies
Implementation standards: GB 712-2000 "Structural steel for hull" and national classification society standards.
Ship board product specifications: 6 ~ 30 × 1400 ~ 3250 × 4000 ~ 12000mm
Shipbuilding steel plates and boiler plates have their own national standards. In addition to the general mechanical properties and welding performance, the special point is that the ship plate requires seawater corrosion resistance, and the boiler plate requires temperature resistance. In fact, the same is the design of the boiler plate.
Shipbuilding steel thin steel plates and thick steel plates produced from ship-made structural steel for the hull structure of ships for ocean, coastal and inland navigation. Structural steel for shipbuilding includes carbon steel and low alloy steel, and the end of the steel number is marked C (ship).
