Application in Shipbuilding and Marine Engineering
Steel is a primary raw material in shipbuilding and marine engineering structures, accounting for 20%–30% of hull and marine engineering construction costs. The main steel products used include:
- Steel plates and section steel (marine bulb flats, H-beams, angle steel, etc.)
- Casting and forging steel
- Supporting welding materials
In hull construction, steel consumption accounts for about 60% of the total ship weight, and sheet metal accounts for 88% of the steel used.
