What is Shipbuilding Steel Plate?
Shipbuilding steel plates are specially designed to meet the high demands of harsh marine environments. LYH Steel supplies premium shipbuilding plates including AH32, DH32, EH32, AH36, DH36, and EH36. These plates offer excellent toughness, high strength, superior corrosion resistance, and outstanding welding and formability properties, ensuring the safety and durability of vessels operating under severe conditions.
Shipbuilding steel must withstand:
- Chemical and electrochemical corrosion from seawater
- Marine biological and microbial corrosion
- Large impacts from waves and changing loads
- Complex processing due to ship structure designs
To meet these challenges, shipbuilding plates require strict standards on chemical composition (Mn/C ratio above 2.5) and carbon equivalent (Ceq). Only certified steel mills approved by classification societies are qualified to manufacture them.

FAQ
Q1:What is the difference between AH32, DH32, EH32 and AH36, DH36, EH36 shipbuilding steel plates?
A1:The main difference lies in their strength levels and application environments.
AH32, DH32, EH32: Suitable for moderate-strength ship structures.
AH36, DH36, EH36: Higher strength grades used for heavy-duty hull structures requiring greater load-bearing capability.
Q2:Why is toughness critical for shipbuilding steel?
A2:Toughness is crucial because ships face severe stress from ocean waves, storms, temperature fluctuations, and corrosion.
Steel plates must resist cracking and deformation under dynamic and impact loads to ensure the vessel’s safety and durability.
At LYH Steel, all our shipbuilding plates are produced with strict quality control to guarantee excellent toughness.
Q3:Are your shipbuilding steel plates certified by major classification societies?
A3:Yes.All LYH Steel shipbuilding plates are certified by leading classification societies, including:
ABS (American Bureau of Shipping)
DNV (Det Norske Veritas)
LR (Lloyd’s Register)
BV (Bureau Veritas)
CCS (China Classification Society)
Each plate comes with a Mill Test Certificate (MTC) and classification approval documentation.
