Steel materials for shipbuilding

Shipbuilding traditionally uses structural steel plate to fabricate ship hulls. Modern steel plates have much higher tensile strengths than their predecessors, making them much better suited to the efficient construction of large container ships.
A particular type of plate is available with a designed-in resistance to corrosion, ideal for building oil tankers. Such steels make possible much lighter vessels than before, or larger capacity vessels for the same weight, offering significant opportunities to save on fuel consumption and hence CO2 emission.
The advanced steels used in these steel-plate applications also find uses in a number of related industries. Offshore oil rigs, bridges, civil engineering and construction machines, rail carriages, tanks and pressure vessels, nuclear, thermal and hydroelectric plants–all these applications benefit from the attributes of modern steels.

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
Easy joining and tight control of potential weld defects
Superior metallurgical properties to overcome brittle fracture/fatigue
Reasonable cost to ensure tangible ROIs

Steel materials for shipbuilding
BBNsteel 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 grade steel: 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 grade steel: Another common shipbuilding steel used to construct and retrofit ship superstructures.
EH36 grade steel: A desirable steel for shipbuilding that is available in prefabricated sections and heavy plates for hull construction and superstructure design.
