CCS AH36 steel is high strength shipbuilding steel with good toughness properties. CCS AH36 steel usually serve the structural requirements of ships, barges, and other types of marineequipment. What is CCS AH36 equivalent steel in GB standard? The CCS AH36 equivalent steel in GB standard is Q345B. It can be proved from below comparision between chemical composition and mechanical property of CCS AH36 steel and Q345B steel.

CCS AH36 equivalent steel Q345B is one kind of Chinese standardized low alloy high tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, Q345B steel possesses the samiliar property of CCS AH36 steel. But CCS AH36 steel is special shipbuilding steel with certificate. CCS AH36 equivalent steel Q345B can not get the certificate proved by the classification society.
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.
