Steel in 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.Basic Ship Construction: Properties of Materials UsedApart from these grades there are another set of grades which are normally used by classification societies which recommend the use of higher tensile strength steel plates to decrease the thickness of plates in larger sized ships to reduce its light displacement. These grades are known as AH, BH, steel grade for shipsDNV Grade A shipbuilding steel plate steel,DNV Grade A steel grade for shipsDNV grade A steel is a kind of hot rolled general tensile strength steel. DNV steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them. The DNV A grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 -

Although stainless steel is very rarely considered as a candidate for ships hulls, its uses throughout the ship and boat-building industry are many and varied, as you will see from this section. Chemical tankers represent the largest tonnage applications, as the primary need is for a material that is strong, easily fabricated, steel grade for shipsStainless Steel Grades - Continental Steel & Tube Companya higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat treated properly. It can be hardened to Rockwell 58 hardness, making it one of the hardest stainless steels. Also known as "razor blade steel". Available in three grades 440A, 440B, 440C (more common) and 440F (free steel grade for ships
