How Are Shipbuilding Plates Classified?

How Are Shipbuilding Plates Classified

There are various classification methods for shipbuilding plates, which can be categorized based on multiple dimensions such as material, strength grade, application and manufacturing process. You can choose the appropriate steel plate according to your specific needs to ensure the quality and safety of the ship.

1. Classified by material:

Carbon steel plate: Its main components are carbon and iron, and it has excellent mechanical properties and welding performance.

Alloy steel plate: On the basis of carbon steel, a small amount of alloy elements are added to enhance the strength, toughness, corrosion resistance or other special properties of the steel plate.

2. Classified by strength grade:

Ordinary strength shipbuilding plates: They meet the general shipbuilding requirements, have moderate strength. And they are easy to process and weld.

High-strength shipbuilding plates: They feature higher yield strength and tensile strength, and are suitable for the construction of large, deep-sea or special-purpose ships.

3. Classification by use:

Steel for hull structure: The main structural parts of the hull, such as the hull, deck, bulkhead, etc.

Steel for Marine machinery: Mechanical equipment on ships, such as engines, propellers, etc.

Special-purpose steels: such as low-temperature resistant steel, corrosion-resistant steel, etc., are used to meet the usage requirements of ships in special environments.

4. Classification by manufacturing process:

Hot-rolled steel plate: A steel plate produced through the hot rolling process, which has good plasticity and toughness.

Cold-rolled steel plate: Steel plates that have undergone cold rolling treatment have high surface finish and dimensional accuracy, but their plasticity and toughness are relatively poor.
