AH36 material is high strength marine steel according to ASTM A131 AH36 material properties. ASTM A131 AH36 material has yield strength of 51,000 psi (355 MPa), and ultimate tensile strength of 71,000 - 90,000 psi (490-620 MPa). ASTM A131 AH36 material supplied by BBN steel can be certificated by LR, ABS, CCS, BV, GL DNV and so on classification societies.

ASTM A131 AH36 material is mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components. ASTM A131 AH36 material also can be used for producing container and bulk cargo vessels as well as cruise ships.
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.
