ABS DH32 High Strength Steel For Shipbuilding

High-strength shipbuilding steel is a special kind of steel used in shipbuilding and has the following remarkable characteristics:

I. Excellent mechanical properties
High strength:
High strength is one of its most prominent characteristics. This kind of steel can withstand huge stresses and ensure the structural integrity of ships in harsh marine environments. For example, in the construction of large cargo ships and container ships, high-strength shipbuilding steel can reduce the amount of steel used, thereby reducing the ship's own weight and increasing the cargo capacity and navigation efficiency.
Its yield strength is usually above 355 MPa, and the tensile strength can reach 490 MPa or even higher. Compared with ordinary steel, high-strength shipbuilding steel can withstand greater loads and provides a solid guarantee for the safe navigation of ships.
Good toughness:
In the marine environment, ships may encounter accidental situations such as wind and waves and collisions. High-strength shipbuilding steel has good toughness and can absorb impact energy to prevent brittle fracture of the steel. Even at low temperatures, this kind of steel can still maintain good toughness to ensure the safe operation of ships in cold sea areas.
For example, the toughness of steel can be evaluated through Charpy impact tests. High-strength shipbuilding steel usually has a high impact absorption energy at low temperatures, indicating that it has good impact resistance.

II. Good welding performance
Welding joint strength:
The strength of welding joints is an important indicator for measuring the welding performance of high-strength shipbuilding steel. Good welding joints should have strength similar to that of the base metal and even exceed the strength of the base metal in some cases. This requires strict control of welding parameters during the welding process to ensure welding quality.
The strength and toughness of welding joints can be detected through methods such as tensile tests and bending tests. The welding joints of high-strength shipbuilding steel can usually meet the relevant standards and specifications for shipbuilding.

 

 

 

IV. Application fields: Ship equipment:
In addition to the hull structure, high-strength shipbuilding steel is also used in various equipment and components of ships, such as cranes, anchor chains, propellers, etc. These equipment and components need to withstand large loads and wear, so they have high requirements for the strength, toughness and wear resistance of steel.
For example, using high-strength shipbuilding steel to manufacture cranes can improve their carrying capacity and work efficiency. At the same time, the corrosion resistance of high-strength shipbuilding steel can also extend the service life of ship equipment and reduce maintenance costs.

The market price of high-strength shipbuilding steel varies due to multiple factors. Different specifications, materials, manufacturers, and market conditions will all have an impact on the price. The following is a rough price range of some common high-strength shipbuilding steels for your reference:
For CCSDH36: The price of Shougang's high-strength ship plate CCSDH36 with a specification of 20mm×2200×10000 is around 4910 yuan/ton.
For AH40, DH40, and EH40: The prices of these types of high-strength ship plates are usually around 4000-4500 yuan/ton.
For CCSA: The price of some CCSA ship plates is around 3900 yuan/ton (such as the ship coil CCSA14mm×1810×C of Handan Iron and Steel).
It should be noted that the market price is constantly fluctuating. It is recommended to pay attention to relevant steel market information or consult specific steel suppliers to obtain the latest price information.
