Plain carbon and mild steel are the most common grades of steel for shipbuilding, as they boast a raft of beneficial properties that make them uniquely suited for marine engineering. These include: High yield strengths and typical tensile strengths on a range of 490 – 620 MPa.
Steel for shipbuilding must first be classified according to one or more of the relevant classification societies: American Bureau of Shipping (ABS), Lloyd’s Register, or Det Norske Veritas (DNV). These have established globally-accepted standards and rules that steel for shipbuilding must follow, from chemical composition to downstream plate thickness.
Key Properties of Steel for Shipbuilding
High yield strengths and typical tensile strengths on a range of 490 – 620 MPa
Easy joining and tight control of potential weld defects
Superior metallurgical properties to overcome brittle fracture/fatigue
Reasonable cost to ensure tangible ROIs
BBN steel is one of the world’s leading suppliers of steel for shipbuilding. All our grades are certified to ASTM/ASME specification and can be classified according to any of the relevant societies. Our steels for shipbuilding include:
AH36: A common steel for shipbuilding that is typically formatted as heavy plates and fabricated surfaces for large, heavy-duty vessels like commercial ships and bulk carriers.
DH36: Another common shipbuilding steel used to construct and retrofit ship superstructures.
EH36: A desirable steel for shipbuilding that is available in prefabricated sections and heavy plates for hull construction and superstructure design.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
