The main form of LR AH40 shipbuilding structural plate and its application

Shipbuilding steel is a kind of steel plate used by shipyards, shipbuilding companies and dockyards to manufacture hulls of cargo and passenger ships, boats, offshore drilling platforms, gateways and other structures and vessels. The company also supply AB AH36 plates and steel sheets LR AH40 shipbuilding structural plate in coils or cut to length, steel profiles (steel bulb flats, rounds and squares), and round and profiled tubes made from shipbuilding steel grades. Shipbuilding steel is produced under the control of certifying societies, sea and river registers.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

As the thickness and hardness of LR AH40 shipbuilding structural plate increase, the tendency to crack at the cutting edge increases. In order to prevent the LR AH40 shipbuilding structural plate from cutting cracks, preheating should be carried out before LR AH40 shipbuilding structural plate cutting. Special attention should be paid to preheating to make the entire LR AH40 shipbuilding structural plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole LR AH40 shipbuilding structural plate cannot be preheated, the partial preheating method can be used instead.
