LR B shipbuilding steel description:

LR B shipbuilding steel plate, B shipbuilding steel plate is the common tensile strength steel. The main features are good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties, and so on.

LR B shipbuilding steel Application range

LR B shipbuilding steel can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons, and usually do navigation around coastal and river area. Also, LR B shipbuilding steel is widely used in oil platform and offshore platform.
