CCS DH40 shipbuilding steel plate is high strength steel with 510-660 MPa tensile strength and 390 Mpa min. yield strength. With high cost and substitutability, CCS DH40 shipbuilding steel plate is favored in marine and shipping industry. According to the classification society rules, CCS DH40 shipbuilding steel plate shall be done low temperature impacting test and normalizing heat treatment.

CCS DH40 shipbuilding steel plate can be accepted with control rolled state if the thickness is under 40mm. But for 40-100mm thk CCS DH40 shipbuilding steel plate, it requests normalizing for each plate. CCS DH40 shipbuilding steel plate can be used to manufacture the hull structure of ships which are not heavier than 10000 tons.
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.
