The difference between marine steel plate and ordinary steel plate

1. The material of shipbuilding steel plate is different from that of ordinary steel plate

Shipbuilding steel plates are usually made of high-strength and low-alloy structural steel or corrosion-resistant alloy steel. This material has high toughness and better corrosion, stress corrosion and fatigue resistance, as well as better cold bending and weldability, and adapts to the special needs of the marine environment.

Ordinary steel plates, on the other hand, are mainly composed of elements such as carbon and iron, and are much simpler, more versatile, and relatively inexpensive than shipbuilding steel plates.

2. The hardness of shipbuilding steel plate is different from that of ordinary steel plate

In terms of material properties, there are also differences in hardness between shipbuilding steel plates and ordinary steel plates. Shipbuilding steel plates are relatively flexible and adapt to the requirements of ocean waves and hull bending Ordinary steel plates, on the other hand, are relatively more brittle and hard, which is more suitable for the needs of the construction and machinery industries that require strength support.

3. The composition of shipbuilding steel plate is different from that of ordinary steel plate

The alloy components in shipbuilding steel plates are mainly several metals, such as tungsten, vanadium, chromium, nickel, manganese, etc. The composition of ordinary steel plates is relatively simple, mainly iron and carbon.

Based on the different compositions, the properties of the two steel plates produced are also different. Ordinary steel plates are more suitable for fields such as manufacturing heavy machinery, building structures, etc.; Shipbuilding steel plates are suitable for the manufacture of ship hulls, underwater equipment, marine technology, etc.

4. The use of shipbuilding steel plate is different from that of ordinary steel plate

Shipbuilding steel plates are mainly used in the field of shipbuilding and marine engineering, and can be divided into structural steel plates, ship plates, oil tank plates, pipeline plates, alumina plates, etc. according to the different use environments.

Ordinary steel plates are widely used in the manufacture of construction plates, mechanical plates, automobile parts, etc.
