Detailed Description of Shipbuilding Steel Plate
Shipbuilding steel plates are hot-rolled steel plates manufactured in accordance with international classification society standards, applied to hull structures and marine engineering equipment. They feature high strength, excellent toughness, superior weldability and good corrosion resistance, capable of withstanding wave impact, seawater corrosion, low temperature environment and complex mechanical loads.

International Classification Society Certifications
CCS, ABS, BV, DNV, LR, NK, KR, GL, RINA
Grade Definition
Grade A/B/D/E: Gradually improved low-temperature toughness (A: 0℃, B: 0℃, D: -20℃, E: -40℃)
AH/DH/EH/FH: High-strength series, letters stand for impact temperature
Z15/Z25/Z35: Lamellar tearing resistance grades in thickness direction
2. Material & Strength Grades
General Strength Ship Plate (Yield Strength ≥235MPa)
Grades: CCSA, CCSB, CCSD, CCSEApplication: Ordinary cargo ships, inland waterway vessels, superstructure
