The main form of CCS DH40 marine steel and its application

CCS DH40 marine steel mainly includes CCS DH40 marine steel plate, CCS DH40 profile (including CCS DH40 angle steel, H-shaped steel, T-shaped steel, I-shaped steel, CCS DH40 bulb flat steel), and CCS DH40 marine steel pipe, among which CCS DH40 steel plate is the most important steel.

As far as the ship itself is concerned, the main uses of various CCS DH40 steels are as follows:
CCS DH40 steel plate is mainly for hull;
CCS DH40 angle steel and profile steel is mainly for hull structure;
CCS DH40 bulb flat steel is mainly for keel;
CCS DH40 steel pipe is mainly for infusion pipe and pressure pipe.

CCS DH40 bulb flat steel is a kind of medium profile steel which is mainly used in the field of shipbuilding and bridge building. In recent years, with the rapid development of flat steel products in shipbuilding industry, there is a strong demand for CCS DH40 bulb flat steel. In the design of large ships and regular ships, most of the main hull is made of marine flat steel, which is the same thickness and material as the connecting marine steel plate.
