What Type Of Steel Is Used In Ships

The primary type of steel used in ships is marine-grade structural steel, commonly known as shipbuilding steel. This steel is specially developed to provide the strength, toughness, and durability required for vessels operating in harsh marine environments. Shipbuilding steel is generally categorized into normal strength grades (A, B, D, E) and high-strength grades (AH, DH, EH, FH series), each designed to meet specific structural and safety requirements. Normal strength steels are typically used for general hull construction, while high-strength steels allow for lighter, more efficient designs without sacrificing safety, making them essential for large vessels, tankers, and offshore structures. These steels also feature excellent weldability and corrosion resistance, ensuring long-term performance against seawater, wave impact, and heavy loads. All grades are certified by leading classification societies such as ABS, LR, DNV, and CCS, guaranteeing compliance with international standards and ensuring reliability in global shipbuilding applications.
